This article points out some things that you might want to know about Alfred Kinsey if you're planning to see or have seen the recent movie based on his life.
In short, he wasn't much of a scientist:
Kinsey, trained as a scientist in the field of zoology, is often credited as the first researcher to use science to address sexual behavior. But Kinsey’s goal was to radically redefine what was considered normal and abnormal behavior. He succeeded in many respects — in large measure, ironically enough, because of his blatant disregard for scientific principles.
You won’t learn about this in “Kinsey.” For instance, as any researcher knows, a scientific study must use a “random selection” model to be considered scientifically accurate and representative of the population. Kinsey used volunteers.
Kinsey’s volunteers were disproportionately comprised of homosexuals, bisexuals, prostitutes and convicts — more in his sample than in society as a whole. So unreliable were his sampling methods that famed psychologist Abraham Maslow, who expressed early interest in Kinsey’s sexuality research, refused to work with him because of his methods.
Predictably, the lack of a true random sample distorted his findings. For instance, Kinsey famously claimed that 10 percent of the general populace is “more or less exclusively” homosexual — 5 percent exclusively gay and 5 percent bisexual. The most recent National Health and Social Life Survey, by contrast, estimates that the actual figure is about 1 percent to 3 percent.
Also, his research in child sexuality is questionable, if not on it's substance, than on it's ethics:
Then there are the questions about Kinsey’s data-collection methods. In his books “Sexual Behavior in the Human Male” (1948) and “Sexual Behavior in the Human Female” (1953), Kinsey cites “technically trained experts” as the source for his data on childhood sexual behavior. In particular, the infamous Tables 30 through 34 in his “Male book” — which charted how long it took to (brace yourself) induce orgasms in children as young as two months old — featured the research of these “experts.”
Today, many knowledgeable experts agree that the source for this information was a habitual pedophile who kept detailed records on the hundreds of young boys and girls he had abused over many years. This character is included in a disturbing-yet-inaccurate scene in the movie that depicts his link to Kinsey as fleeting and inconsequential. In reality, Kinsey had a longstanding professional relationship with this man and included an untold amount of his records and notes in his “research.”
I'll make no comment on this. The material speaks for itself.
