95 Emotions are an evolutionary device to focus attention on immediate problems.\nThey are used to evaluate the best outcome in an array made of pieces of information that aren't always coherent.\n\nIt would be too costly to compute (think about) them all.\n\nEmotions are a mean to maximize positive outcomes, they are a fast shortcut to good generic rules.

100 Children living with step-parents have a higher level of cortisol than \nchildren living with any other kind of relatives\n\n\nThis is interesting, this happens even in the case of a children living with a remarried mother.\n\nConsequently, living with the grandparents is less stressful than living with a remarried mother. Children living with anyone other than parents -> More stress Flinn, Mark V., and Barry G. England. "Childhood stress: endocrine and immune responses to psychosocial events." Social & cultural lives of immune systems (2003): 107-147.
105 Fitness is enhanced by resources and commodities such as food, shelter, territories, and mates.\n\nResources might become scarce and individuals might want to leave. Such choice carries costs: The new location might not have enough resources of might be inhabited by strangers which will lead to fights.\n\nAggression is one of the responses to competition for resources.\n\nThere are costs to leaving and costs for fighting for resources. Resources -> The main source of conflict Campbell, Anne. "Aggression." The Handbook of Evolutionary Psychology (2015): 628-52. Web.
106 Aggression has costs.\n\nIn zero sum games, competitions were there are only one conclusion, an individual has to chose the best option: fight or flight, reward or cost.\n\nIf we wanted to calculate it, it would be similar to:\n\nReward * (Probability - Cost * Probability)\n\nThere are two types of aggression: Proactive and responsive.\n\n* Proactive:\nAbsence of anger and arousal, it's a mean to an end.\n\n* Responsive:\nIt's a response with anger and emotions.

110 Humans have an inner desire to punish those who enjoy benefits without paying costs, it triggers the emotion of anger.\n\nThis desire doesn't apply when it's children and disabled persons enjoying benefits without paying costs.\n\nThe fitness of a "punisher", someone who puts a cheater back on track, depends on the number of "free loaders" in the current population.\n\nIf there is only a small number of "free loaders" it is advantageous to be a punisher, otherwise it is too costly. Angers at individuals who enjoy benefits without cost -> recalibrate society with "police" only if small number of "free loaders" Fehr, Ernst, and Simon Gächter. "Altruistic punishment in humans."

111 Protecting and defending oneself from threats and attacks is an automatic adapted behavior.\n\nFor instance, we focus and notice directly angry facial expressions, the rapid approach of an object or person, and the sight of weapons.\n\nThose threats trigger strong responses.\n\nIndividuals also consider out-groups as threats, which plays a role in in-group preferences and out-group avoidance.\n\nThe group membership of another person, itself, might trigger the anti-threat mechanism. Adaptation to danger -> Directly notice threats -> Avoid threats Ackerman, Joshua M., et al.

113 The in-group/out-group preferences increase as much as the individual dependency on the group.\n\nThe in-group morals weight so much that even un-threatful out-groups can be seen as dangerous if they have different morals.\n\nIt entails conflict in the absence of threats and competition.\nThey become target simply by following their norms. Individual depends on the group -> In-group bias -> Individual wants conflict with out-groups with different moral values Henrich, Joseph, and Francisco J. Gil-White.

123 The view on how resources are shared depends on the person's own status:\n\n* If someone is socially dominant they will prefer hierarchical relationships and distributions based on merit.\n\n* If someone is low on social dominance they will favor social qualities and distributions based on needs.

72 In a life or death situation kin altruism is curvilinear (U-shaped) depending on age.\nMeaning that we help more the younger and older aged people than the rest.\n\nWomen are also favored over males in the case where they are younger than 45yo. If not they receive the same treatment.\n\nAltruism with others is also possible if the cost and risks of investment are low (see Hamilton's rule).\n\nThe overall rule is that help is directed at advantaging the vulnerable.\n\nHelping others is also a sign of abundance and power.\nMales that are altruist show those features.\n\nDoing the opposite, not helping at all, can hurts someone's status.

117 Because of the importance of status, changes in it directly affect the individual's physiology by the medium of hormones.\n\nChanges in status can mean the difference between life or death.\nThe body responds to it with stress: cortisol and adrenaline.\n\nThe short term effects are to mobilize energy taken from the fat storage and to make the heart beat fast, pumping blood throughout the body.\n\nThe long term effects are to alter the fat storage mechanism, create an hormonal imbalance, sleep disturbance, and altered mood.

132 Social/Game theory is an important field related to evolutionary psychology.\n\nIt involves studying the evolution of social behaviors in game like environments. Because game scenarios are like real social conflicts it can be applied to group dynamics.\n\nOne of the best strategy is the "Tit for tat" which is a winner in most populations.\nIt consists in acting "kindly" on first encounter and "roughly" if the partner doesn't cooperate.\n\nThis type of strategy is called an altruistic strategy.\n\nAltruistic strategies open the door for selfish ones to flourish.\nIn a population where tit for tat won over the equilibrium, totally altruistic strategies (no reprehension at all) can spread and in theory would not be distinguishable from tit-for-tat.\n\nIn this case it would leave an advantage to abusers to abuse the totally altruistic strategists.\n\nPeople can assess if another person will cooperate by checking their status, norms, and reputation or by using their social biases.\n\nAll in all the composition of a population affect the dynamics and strategies the people can take.

142 The role of female orgasm is still unclear.\nHowever studies have shown that if it happens 1 min before or 45 min after ejaculation there is a higher chance of retaining sperm.\n\nIt is hypothetical that this will result in a bigger likelihood of conception.\nRetaining sperms doesn't mean a higher chance of conception.\n\nThe concern men show about whether their partner achieves orgasm or not might signify that female orgasm has an evolutionary role.

148 Personality is a mix of the following:\n\n* A range of heritable alternatives mechanism to deal with the world.\n\n* Traits created by situation dependent mechanism.\n\n* A momentarily calibration to the events or environment.\n\nNot all strategies/personalities are viable in a population.\nSome populations restrict thoughts because of its environment and norms.\n\nOn the opposite, the more a society allow free interaction between its members, the more there will be different personality types.\n\nLet's also note that if an optimal personality trait emerges in the current environment, no new trait will appear different from it.\n\nFitness traits and personality traits are favored if passed genetically and show a high genotypic variance and variability.\nThis means the traits are clearly discernible, making a difference between individuals that have it and those who don't.\n\nMen tend to have personality traits that go along with dominance, extroversion, and risk taking.\nWomen tend to have personality traits that go along with nurturance and love.\nThose are all clearly discernible traits.

7 First born are more likely to stay in long term relationships and defer gratification; they prefer stability but are overall more anxious.\n\nLater born are more likely to strive for variety and excitement; they also have a more relaxed life.\n\nThis is related to anxiety felt from the parents' expectations, which highly affects self-esteem.\n\nHowever, those studies have been conducted erroneously by being done by assessments within the same family.

10 Affection, and bonding between parents and children is the root of future violence and dis-functions as adults.\n\nThe more a society experiences pleasure the less it inflicts pain and\nvice-versa.\n\nSocieties with a strong denial of body contact and shaming of natural\ninstincts have the highest rate of violence.\n\nIn those societies products enhancing violence are approved but not the ones who are pro-pleasure.\n\nFor instance, alcohol is allowed but not marijuana.\n\n\nThere’s a correlation between marital non-sexual\nsatisfaction, somatosensory deprivation (denial of body contact) and\nnon-affectionate parents, and extramarital affairs.\n\nPeople have extramarital affairs because they have lost the ability to bond with their partner. They jump from one person to another in\nthe hope it’ll be better.\n\nLike with alcohol, anything acts as a suppressor of\nthe pain inflicted in childhood.

43 In a society where there is a lot of female infidelity men invest more in their sisters' children than in their own.\n\nThey have more proofs that they share genes with their sisters than their children.\nWhen women cheat there is low proof of paternity.\n\nThis mechanism redirects the resources unto someone sharing at least 1/8th of his genes (Hamilton Investment Theory).

44 The offspring survival rate and quality depends directly on parental investment.\n\nIn a society where the cost of investment in children is high and the cost of having other mates is low there is more male abandonment.\nThe men are more likely to leave the couples.\n\nOn an opposite side the notion of concealed ovulation, dispersed mates, and low investment cost are correlated with high paternal investment.\nIn this case it is favorable for the men to invest in the children.

46 Facial similarities affect investment in others.\n\nThe more similar the faces, the more trust, and resource investment there is.\nIf they are close in their features it is an: Identity By State (IBS)\n\nThe closer they are linked, in their relationship genetically, the lesser they are sexually attracted.\n\nThis coefficient or relatedness is the: Identity By Descendant (IBD)\n\nMen are more able to discern facial similarities than women.\nThis device is used as defense against cuckoldry; they can directly notice if the child is rightfully theirs.

47 There is a higher child mortality rate in high risk societies.\nIt correlates with low investment in children and with adults seeking more mates.\n\nIn the cases where parental investment is present, children have better social competitiveness and by consequence have a reproductive advantage over their peers which have no parental investment.

61 Women from the moment of conception invest highly in their children.\nBecause of this they can differentiate between healthy fetus and non-healthy ones.\n\nOnly 60% of fertilized eggs implants in the uterus, 20% of those are miscarried. Furthermore, if a fetus doesn't secrete enough HCG (hormone) it won't survive the development phase.\n\nThe environment also plays a role in early miscarriage. For instance, danger and stress are correlated with an increase in miscarriage.\n\nThose are natural "abortion" and investment redirection mechanism. There are priorities and the body knows it.

86 It is risky for a women to copulate, get pregnant and be left alone to take care of the child.\nConsequently they refuse to copulate, use "coyness" and "domestic-bliss", to spot signs of infidelity and recognize the qualities of her mate before opening her bed.\n\nFor example, women want to be sure of certain qualities, assess them before rearing a child: Nest, food, security.\n\nMales are more tempted to leave after copulation and this sort of mechanism prevents that. It makes sure they invest enough and are less likely to depart.\n\nOn a side note, liars use this method to get "free" sex from women.\n\nOn the men part, they can also use "long engagement periods" to make sure the women won't sway or they are already pregnant from another man's children.\n\nMoreover, the more time and energy a couple spends together, the less likely they are to break up.

92 Infants develop social skills before physical ones.\nThey have an elastic brain that quickly learns social rules.\n\nIt makes us realize the important of adaptation to the local community: language, facial recognition, eye contact, facial expression, etc..\n\nBecause it takes a long time for infants to be physically able there is a need for long parental investment, for caretakers.

101 Household factors to raise stress (cortisol):\n\n* Children living in houses with quarreling and fight have abnormal peaks and fluctuations of cortisol.\n\n* When the father leaves the house and returns the cortisol level of the children raises and falls back upon return.\n\n* Traumatic events increase cortisol by 100% to 2K% compared to normal raise, which varies between 10% to 100%.\n\nChronic stress has long lasting risks on children:\n\n* It blunts the responses to normal and useful stress.\n\n* The chronically stressed children have a bellow average cortisol level during "normal" situation and appear socially "tougher".

150 Important facts about memory:\n\n* It maintains items once added to long term memory.\n* It keeps them in a flexible form.\n* It silences irrelevant information.\n\nWe selectively remember information because it is too costly to remember everything.\n\nAn example of this is the childhood amnesia from abuse. It's role is to protect the child from the knowledge that a key caregiver may be a perpetrator. Which is a prerequisite for maintaining a crucial relationship/survival.\n\nWhen missing clues from the past people go back and create steps that could possibly lead to the same judgment, reinforcing the biases and prejudices. This is called the "confirmation bias".\n\nSmall samples of memory act like biases, together they form correlations and shortcuts of thoughts.\n\nIn a world where the environment constantly changes, literally recalling information is unimportant.\n\nWhen making decisions people simply weights the choices against each others.\n\nIt is easier to process and make decisions about information related to ideas that come from a longer evolutionary time than the ones that just recently appeared in the human world.\n\nIt's easier to deal with the fear of fire than the fear of walking on the highway.

109 The thought of future interactions makes people more aware of their reputation, especially when it's for future cooperation.\n\nThe opposite is also true, anonymity creates selfishness and antisocial behaviors.\n\nThe commitment to future interactions gives rise to group commitment. \n\nIndividuals do public performances to show their attachment to the group.\n\nSocial familiarity gives rise to long future commitment and an increase in the likelihood of pro-social behaviors.

118 A change in status might induce stress or it might not in some cases.\nThe opposite is also true: Stress can lower someone's status, and being relaxed can rise someone's status.\n\nHow an individual reacts in a particular situation reflects their social status and their quality of life.\n\nFor example:\n\nCompetitive games and contests psychologically feel like real contests between rivals:\nThey include the fight for status in the hierarchy and thus induce stress.\n\nPoverty is highly correlated with stress because of its effect on status.

122 Societies with rigid rules are more stable; they are characterized by rigid social hierarchies.\n\nThe drawbacks are the loss of individuality and individual freedom.\nPeople have an obligation to learn and follow the rules.\n\nThere are more stereotyped persons in those societies.\nEveryone is typical and falls into a category.

127 A loss of status or facing someone with better status induces many different feelings:\n\n* A deep sense of shame\nIt is characterized by the avoidance of eye contact, lower chin, avoiding social encounter, etc..\n\n* Rage and depression, or submissive behavior\nUsed to appease others and avoid future humiliation.\n\n* Envy\nDue to a loss or inequality in status.\nThis specific emotion can trigger destructive behavior, especially if the subject field is one that the individual is deeply involved.\n\n\nThe degree to which someone is satisfied with one-self has also an effect on status, the so called self-esteem.\n\n\nPeople prefer others that make them feel good about themselves.\n\nBy consequence, the ones that are targets of envy make others feel bad: The discomfort they entice triggers others to attack their status.\nFor example using: gossip, malicious acts, etc..

130 Biases are design features.\n\nThey arise when no evidence of logic is found and work as shortcuts, which are valid in many cases.\n\nThey are useful in situations where there are processing limitations or processing all available choices is too costly.\n\nThey are also created for tasks that the mind has not been designed to conceive, abstract concepts.\n\nIf processing is not costly than the bias is removed if and only if it affects the reproduction process.

134 Depending on the situation, the way we think of something differs.\n\nIt is contextual.\n\nUnder pressure we cannot think of all the complex alternatives and thus use shortcuts or simple rules based on past scenarios, we use biases.\n\nBiases are multiple rules defined for multiple situations.\n\nIt has in assumption that a false positive is always better than a false negative.\n\nFor example: People avoid eating the same food if they get sick right after eating it. Even in the case where the sickness wasn't related to the food.\nThe opposite case, where it was indeed induced by the food, can be fatal.

139 In the inculcation of morality conditioning, vicarious learning, and the identification plays a bigger role than social learning and reasoning. \n\nSocial learning and reasoning are overrated, they aren't as important as it seems in the transmission of norms.\n\nLet's also note that societies are supported by reward and punishment.\nIf there are no punishment there will always be defectors breaking rules, behaving immorally, and cheating.\nIt is advantageous for them.

143 Parents invest in children that have the most profitable return reproduction wise.\n\nThere is a difference in how the sex of the children affect this investment.\n\nBoys:\nIn the future they can have many offspring with multiple partners. To achieve this they have to compete against other males for mates.\n\nGirls:\nIn the future they are assured offspring but are limited in the number of children they can have.\n\nThere is a tendency for couples with abundant resources to invest more in boys and for resource-poor couples to invest in girls.

149 After mate choice, a mental mechanism takes place in ones mind to prevent wandering from the current mate.\n\nWhen committed to the relationship, there's a positive bias toward the partner and a negative on towards potential mates. Committed to relationship -> Positive bias towards partner Simpson, Jeffry A., Steven W. Gangestad, and Margaret Lerma.

155 The most desired traits in partners are:\n* Kindness\n* Understanding\n* Intelligence.\n\nOther desired traits:\n* Considerate\n* Honest\n* Affectionate\n* Dependable\n* Interesting to talk to\n* Loyal\n\nSpecific traits for women:\n* Physical attractiveness\n* Good cook\n* Frugal\n\nSpecific traits for men:\n* Good earning\n* Dependable\n* Ambitious\n* Good family background\n* Altruism\n* Tall\n\nIt's also important to note that individuals prefer similarity mating, people with the same traits, more than complementary mating.\n\nThe theory behind similarity mating or genetic similarity theory is the following:\n\nIf the phenotype matches the persons are more close genetically (Identity by State) and thus preserving the coherence of their genome.\nIt consequentially increases the relatedness of parents to children.\n\nOn a side note, older couples prefer choosing partners that are less similar to themselve.

156 As a general appreciation of personality:\n* Men prefer tender-minded partners.\n* Women prefer tough-minded partners.\n\nThe couple marital satisfaction is lower when the man in the couple has high libido.\nThis fact is unrelated to the woman's libido.\n\nDissimilarities, the differences in personality between partners, is correlated with divorce.

160 Sexual intercourse issues between the genders:\n\n* Men have problems with premature ejaculation.\nIt might have been favored because of the advantage it gives when the time for copulation is limited, or stressful, or dangerous.\nThis problem is more frequent in young, fearful, and stressed men.\n\n* Women have the opposite problem.\nThey have issues reaching orgasm, taking more time to achieve it.\nIt might have been favored so they have fewer children and focus on choosing only the best partners, the ones who take the time to please them.

169 The big five personality traits, OCEAN are heritable at around 50%.\n\n* Openness to experience\n* Conscientiousness\n* Extraversion\n* Agreeableness\n* Neuroticism\n\nThe other 50% are due to social norms and environmental factors.\n\nThose traits gets more stable as time goes on.

172 Top 10 Replicated Findings From Behavioral Genetics:\r\n\r\n* All psychological traits show significant and substantial genetic influence\r\n* No traits are 100% heritable\r\n* Heritability is caused by many genes of small effect\r\n* Phenotypic correlations between psychological traits show significant and substantial genetic mediation\r\n* The heritability of intelligence increases throughout development\r\n* Age-to-age stability is mainly due to genetics\r\n* Most measures of the "environment" show significant genetic influence\r\n* Most associations between environmental measures and psychological traits are significantly mediated genetically\r\n* Most environmental effects are not shared by children growing up in the same family\r\n* Abnormal is normal Traits are not 100% inherited but genes have a great influence Plomin, Robert, John C.

173 Political affiliations can be heritable. It is an extended phenotype, an indirect consequence of the five big genetically heritable behavioral traits.\r\n\r\nSo as with any other behavioral traits it's half heritable.\r\n\r\nThis is especially true for:\r\n* Openness to experience\r\n* Agreeableness\r\n* Neuroticism\r\n\r\nRelated to sharing resources, males wich are more dominant or physically able support distribution based on merit and males which are less dominant support distribution based on needs. For females it is less clear. Political affiliation is an after effect of behavioral traits "Biology and Political Orientation." Wikipedia. Wikimedia Foundation, 11 Mar. 2017.
