While the book is fascinating (morbidly), the science is super flawed (SUPER DUPER INCREDIBLY) and it’s very odd that this is such celebrated information, even to this day among academics. His sampling was skewed interviewing an unequal number of men and women, and I haven't been able to find out too many other specifics about this pool, religion, age, sexual orientation etc.. which are often particularly with sex influencing factors (I am going to assume, that the data is not discussed because the data was not gathered) the one thing that was clear is that all participants where Caucasian.
It was also self-reported data, almost exclusively, which can be revealing but is also super prone to bias, because not just in the selection of the participant like I said before. But people will lie to be more socially acceptable, and/or easily influenced by the interviewer, also this data in transcription can be intentionally or unintentionally "rewritten" so a very detailed multilayer check that everything went from point A to point B correctly is important (haven't found comment one way or the other on that). PLUS (as if we need more evidence) there can be "leaving out" information that does support your thesis/hypothesis which is totally unethical but also does happen!
UPDATE : After some poking around, this "science" as it relates to academia and its reputation. Kinsey seems to have suffered (or rather profited) from Daisy Chaining, where it was (semi-demi) credible at the time and was thus cited, and then people have cited the cited work, which is then cited, again and again and again. All the while people haven't really returned to the source info, hence the diluted generalities that Kinsey put forward are now acceptable (even though the foundation of that acceptability is built on nonsense). I am pretty sure I have heard this called something like "sand-castle-ing".
Additional and most disturbingly there is a good chunk of evidence to suggest that Kinsey seems to have been a pedophile,
Specifically in this work I can reference specifically table 34 where he talks about orgasm in babies and children which is prefaced and followed by the sexuality of children… there have been pretty substantial ethical grounds to say he abused at least 300 minors in his official work, which is on record. Kinsey also harped, excessively on how sex is not moral or immoral, which in itself is not a bad thing, but it was a lack of shame towards things like pedophilia (prepubescents), hebephilia (teenage), rape, other philias (which are no inherently harmful but do tend to have harmful fallout/casualties) that are concerning. There is a weird strawman that crops up here where Pro-Kinseyians will shout about homophobia and shaming a gay man. Its not the homosexuality that is the issue, its that he had a sexual preference for little boys. If he liked men, not an issue, predatory behavior towards children = huge huge huge HUGE problem.
So I will admit there are take always from, this text and not just this text but Kinsey’s other books but it HAS to be acknowledged that be worked primarily with deviants (pedophiles and prisoners) to get a lot of his information, the non-pervert info was not good quality at all and that the man was a pervert.
