Jonathan Mooney: "The Gift: LD/ADHD Reframed" - YouTube
"The University of Oregon Accessible Education Center and AccessABILITY Student Union present renowned speaker, neuro-diversity activist and author Jonathan Mooney.

Mooney vividly, humorously and passionately brings to life the world of neuro-diversity: the research behind it, the people who live in it and the lessons it has for all of us who care about the future of education. Jonathan explains the latest theories and provides concrete examples of how to prepare students and implement frameworks that best support their academic and professional pursuits. He blends research and human interest stories with concrete tips that parents, students, teachers and administrators can follow to transform learning environments and create a world that truly celebrates cognitive diversity."

How the Idea of a 'Normal' Person Got Invented - The Atlantic
"The notion that there is a “normal” height or a “normal” salary is a relatively new one, and it's had a profound effect on how people think about each other and themselves."
;

"In the early 1840s, Quetelet analyzed a data set published in an Edinburgh medical journal that listed the chest circumference, in inches, of 5,738 Scottish soldiers. This was one of the most important, if uncelebrated, studies of human beings in the annals of science. Quetelet added together each of the measurements, then divided the sum by the total number of soldiers. The result came out to just over 39 ¾ inches—the average chest circumference of a Scottish soldier. This number represented one of the very first times a scientist had calculated the average of any human feature. But it was not Quetelet’s arithmetic that was history-making—it was his answer to a rather simple-seeming question: What, precisely, did this average actually mean?

It seems like the answer would be obvious, but it’s not actually clear what the significance of average size is. Is it a rough guide to the size of normal human beings? An estimate of the size of a randomly selected person? Or is there some kind of deeper fundamental meaning behind the number? Quetelet’s own interpretation—the first scientific interpretation of a human average—was, not surprisingly, conceived out of concepts from astronomical observation.

Astronomers believed that every individual measurement of a celestial object (such as one scientist’s measurement of the speed of Saturn) always contained some amount of error, yet the amount of aggregate error across a group of individual measurements (such as many different scientists’ measurements of the speed of Saturn, or many different measurements by a single scientist) could be minimized by using the average measurement. In fact, a celebrated proof by the mathematician Carl Gauss appeared to demonstrate that an average measurement was as close to a measurement’s true value (such as the true speed of Saturn) as one could ever hope to get. Quetelet applied the same thinking to his interpretation of human averages: He declared that the individual person was synonymous with error, while the average person represented the true human being.

After Quetelet calculated the average chest circumference of Scottish soldiers, he concluded that each individual soldier’s chest size represented an instance of naturally occurring “error,” whereas the average chest size represented the size of the “true” soldier—a perfectly formed soldier free from any physical blemishes or disruptions, as nature intended a soldier to be.

Quetelet followed the same line of reasoning with regard to humanity as a whole, claiming that every one of us is a flawed copy of some kind of cosmic template for human beings. Quetelet dubbed this template the “Average Man.” Today, of course, someone described as “average” is implied to be inferior or lacking. But for Quetelet, the Average Man was perfection itself, an ideal that Nature aspired to, free from error. He declared that the greatest men in history were closest to the Average Man of their place and time.

Eager to unmask the secret face of the Average Man, Quetelet began to compute the average of every human attribute he could get data on. He calculated average stature, average weight, and average complexion. He calculated the average age couples got married and the average age people died. He calculated average annual births, average number of people in poverty, average annual incidents of crime, average types of crimes, the average amount of education, and even average annual suicide rates. He invented the Quetelet Index—today known as the body mass index, or BMI—and calculated men’s and women’s average BMIs to identify average health. Each of these average values, claimed Quetelet, represented the hidden qualities of the Average Man.

As much as Quetelet admired the Average Man, he held an equal amount of antipathy toward those unfortunate individuals who deviated from the average. “Everything differing from the Average Man’s proportions and condition, would constitute deformity and disease,” Quetelet asserted. “Everything found dissimilar, not only as regarded proportion or form, but as exceeding the observed limits, would constitute a Monstrosity.” He also pronounced, “If an individual at any given epoch of society possessed all the qualities of the Average Man he would represent all that is great, good, or beautiful.”

Though today an average person isn’t thought to embody perfection, it is presumed that an average person is a prototypical representative of a group—a type. There is a powerful tendency in the human mind to imagine that all members of a group—such as “lawyers,” “the homeless,” or “Mexicans”—act according to a set of shared characteristics, and Quetelet’s research endowed this impulse with a scientific justification that quickly became a cornerstone of the social sciences. Ever since Quetelet introduced the idea of the Average Man, scientists have delineated the characteristics of a seemingly endless number of types, such as “Type-A personalities,” “neurotic types,” “micro-managers,” and “leader types,” arguing that useful predictions could be made about any given individual member of a group simply by knowing the traits of the average member—the group’s type.

Since Quetelet’s concept of the Average Man seemed to impose welcome order on the accelerating jumble of human statistics while simultaneously validating people’s natural urge to stereotype others, it’s little wonder his ideas spread as they did."

The Aporeticus - by Mills Baker · Design & Compromise [So much more within, read the whole thing and the comments too.]
"…why does compromise have its “undeservedly high reputation”?…b/c we are discomfited by philosophical implications of fact that some ideas are objectively better. We exempt science from our contemporary anxieties because its benefits are too explicit to deny, but in most creative fields we are no longer capable of accepting the superiority of some solutions to others; unable to sustain confidence in soundness of artistic problem-solving process, we will not provoke interpersonal/organizational conflict for sake of mere ideas.

This sad, mistaken epistemological cowardice turns competing hypotheses into groundless, subjective opinions, & reasonable course of action when managing conflicting, groundless opinions…is to compromise, because there is no better answer.

But the creative arts are not so subjective as we tend to think, which is why a talented, dictatorial auteur will produce better work than polls, fcus groups, or hundreds of compromising committees."
