BEHAVIOUR AND DEVELOPMENT -- RACIAL DIFFERENCE

Behaviour and Development

>The ability to think ahead and prepare for the future is inversely correlated with impulsiveness.[63]

>Among Whites and Blacks earning more than $50 thousand per year, Blacks saved less than half the average amount that Whites saved.

>Instant gratification is normally considered an infantile/immature trait; In Africa where Whites taught Blacks how to farm effectively, they increased their production by 10x - but when they returned 2 years later, the Blacks already reverted to their previous behavior.

>Impulsiveness is also correlated with drug abuse and crime, where Blacks consistently outperform Whites (see next section on crime). In one experiment, Black and White children were offered a small candy bar immediately or a larger one later: most of the Blacks chose the small one and most of the Whites chose the larger one. The author wrote "Negroes are impulsive, indulge themselves, settle for next to nothing if they can get it right away, do not work or wait for bigger things in the future."

>According to one author, Blacks "hold labor as an evil inferior only to death… There is abundant evidence to show that the Negro will not work without a considerable amount of persuasion."

>There were few if any evolutionary selective pressures for future preparation in Africa while Europeans who did not plan ahead for the cold, hard winter would have starved to death and not have passed on their genes. This process slowly weeded out, through countless generations, the inability to properly plan ahead in White populations. "In tropical environments [such as sub-Saharan Africa] where food is available all year round, hunter-gatherers rarely store food even overnight."

>Blacks are significantly more sexually active than Whites
http://psychology.uwo.ca/faculty/rushtonpdfs/Race_Evolution_Behavior.pdf

>Their sex drive is about 37% greater.

>46% of Black males reported having at least 15 sexual partners, more than any other race.

>In 2009, Black women aged 10-19 had a 6x higher birth rate than White women of the same age and illegitimate births were 2.5x higher for Blacks than Whites.

>Roughly half of all HIV/AIDS cases are amongst Blacks, despite being only 13% of the US population.
http://www.avert.org/usa-race-age.htm

>The Black chlamydia rate is 8x the White rate, the gonorrhea rate 18x, and congenital syphilis 15x. 40% of Black adults have genital herpes compared to 14% of Whites, and nearly half of black girls aged 14-19 have at least one STD, compared to 20% for white girls.

>The tendency of sexual promiscuity has been common in Africa for thousands of years while monogamy was religiously practiced in Europe. The hormone-driven feeling of falling in love is an adaptive trait that induces pair bonding and reduces the attractiveness of others.

>The largest relative brain sizes among primate species are associated with monogamous mating systems.
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1762360/

>Sexual promiscuity is universal in African populations, suggesting that this behavior is biologically based.

>Altruism, the desire to help other people, including strangers, appears to be genetic
http://www.sciencemag.org/content/311/5765/1301.abstract

>Whites seem to be the most altruistic based on donations of money, blood, and organs. People with a specific allele of the AVPR1a gene are more altruistic, although racial differences have not been studied.
http://www.ncbi.nlm.nih.gov/pubmed/17696996

>One study found evidence that Blacks have more in-group empathy than Whites, stating that "African-Americans showed greater empathy for African-Americans facing adversity - in this case for victims of Hurricane Katrina - than Caucasians demonstrated for Caucasian-Americans in pain."
http://www.ncbi.nlm.nih.gov/pubmed/17696996

>The PER2 gene on Chromosome 2 "is a key component of the mammalian circadian clock machinery… [a] high and significant difference in the geographic distribution of PER2 polymorphisms was observed between Africans and non-Africans."

>The MAOA-L gene has been linked to aggression, antisocial behavior, impulsivity, impaired impulse control, gang membership, and other negative behavioral traits.

>The 3-repeat allele has been shown to cause increased aggression in humans, and 59% of Blacks have this allele compared to 34% of Whites.
http://journal.nzma.org.nz/journal/120-1250/2441/

>13.5% of Blacks have the extreme aggression 2-repeat allele as opposed to 1% of Whites.
http://www.ncbi.nlm.nih.gov/pubmed/16896926

>MAOA-L has been dubbed the "Warrior gene" and a growing body of evidence has linked it to strong evolutionary selective pressures.
