Genetic Disorder Removes Racial Bias and Social Fear

People who suffer from a rare genetic disorder called Williams Syndrome have a complete lack of social fear. They experience no anxiety or concerns about meeting new people or being put into any social situation, and a new study by Andreia Santos suggests that they also don't have any racial bias. From the article: "Typically, children start overtly gravitating towards their own ethnic groups from the tender age of three. Groups of people from all over the globe and all sorts of cultures show these biases. Even autistic children, who can have severe difficulties with social relationships, show signs of racial stereotypes. But Santos says that the Williams syndrome kids are the first group of humans devoid of such racial bias, although, as we’ll see, not everyone agrees."

    Maybe you don't understand. Toddlers have racial biases. Even babies just a few months old will prefer to look at a picture of someone with the same skin color as them. It's built into the way our brain works. These kids don't have that at any age. They also don't have the subconscious biases that 99% of people have, even the people that are nice to everyone and would never say, do, or even think a racist thought.

    Though, interestingly, the study also tested for sex-linked biases, on which the disorder has no effect.

    The fear or distrust of "same as us but not one of us" is common.

    Many species of social animals (mainly larger predators: wolves, lions, etc.. ) act threatened when confronted with a different pack, pride, colony, etc of their own kind... more so than by the presence of a different species (such as humans).

    There's a damn good reason for it too. The group recognizes that other "tribe" of us wants the exact same thing we need to survive.

    Williams Syndrome usually comes with a below average IQ, ALWAYS comes with connective tissue issues, including moderate to severe heart disease. It almost always comes with a reduced size, and different than "normal" facial features.

    oh yeah and there is some social stuff too :P

    This is a really cool on-line rather objective test for determining what racial color biases you have:

    https://implicit.harvard.edu/implicit/demo/

    This really really pisses off people who think they have no prejudice.

    *** Spoiler Alert ***
    To do well on the test (and get a neutral rating), you really have to accept the racial bias you have and actively prompt yourself to counter it.

    This has the messy details. Highlights include:

    "The majority of individuals with Williams syndrome have some type of heart or blood vessel problem. Typically, there is narrowing in the aorta (producing supravalvular aortic stenos is SVAS), or narrowing in the pulmonary arteries. There is a broad range in the degree of narrowing, ranging from trivial to severe (requiring surgical correction of the defect). Since there is an increased risk for development of blood vessel narrowing or high blood pressure over time, periodic monitoring of cardiac status is necessary. "

    "Most people with Williams syndrome have some degree of intellectual handicap. Young children with Williams syndrome often experience developmental delays; milestones such as walking, talking and toilet training are often achieved somewhat later than is considered normal. Distractibility is a common problem in mid-childhood, which appears to get better as the children get older. Older children and adults with Williams syndrome often demonstrate intellectual "strengths and weaknesses." There are some intellectual areas (such as speech, long term memory, and social skills) in which performance is quite strong, while other intellectual areas (such as fine motor and spatial relations) are significantly deficient."

    There are a number of other potentially nasty medical issues, as well as the personality features that make the sydrome interesting to researchers in human behavior, psychology, and neurology.

    As far as I know, the stuff specifically pertaining to "Racial bias" is completely harmless, and it is pretty fascinating that such a dramatic psychological effect can be caused by a single mutation. The "Lack of social fear" stuff isn't directly harmful; but I'm sure that "developmentally disabled child who loves and trusts everybody, and doesn't recognize social danger signals" goes badly from time to time.

    However, its the cardiac, circulatory, and cognitive issues that really make this one a serious disorder.

    Do you actually understand the concept of statistical significance? From your use of the word 'insignificant' I doubt you're really understanding what the article is saying. Statistical significance is a different concept from what is typically meant by 'significance.'

    I'm probably oversimplifying a bit, but the error bars on the Williams bar in the figure is sufficiently large to include 50% ('pure chance'). This means that based on the number of children tested, the standard deviation around the estimated mean includes the chance value--therefore, we cannot say with any confidence that the 'true' mean differs from 50% in Williams children.

    In contrast, the error bar around the non-Williams children comes nowhere near 50%--that is, there is no reasonable way that resampling would produce a mean of 50%. Therefore the 'true mean' must be significantly different from 50%--and in this case, it is different in the direction of greater bias.

    until the late 1990s it was diagnosed by facial features and behavior. There is a very simple genetic test for it now (it shows up on a FISH test). Due to being in multiple WS societies/clubs I am in contact with many different levels of functioning in people with WS. I know a professional, barred, practicing lawyer who (we are 99% sure) has WS. But there is a big problem with high functioning people getting a diagnosis. WS is still considered to be "mental retardation" even though not all cases result in a below average IQ, so a professional lawyer CANNOT get diagnosed or he risks his license. We have met several people whom a geneticist would Diagnose on sight for sure, just based on the facial structure and eyes (blue with white starburst) but it is not a great idea to get saddled with what amounts to a "retarded" diagnosis, when you are high functioning.

    also co-existance of Autism and WS is common, like 10-20% of subjects who have ws
