Mathematical explanation

[edit]

I think it would be nice to include a plot explaining the alternative explanation - a mathematical artifact of using ratio instead of a line described by slope and intercept to model the data. Not sure if I can upload an image.. http://imgur.com/K4doEjJ

File:Ratio of points on line with non-zero intercept.gif
Ratio of points (violet) sampled from a line with non-zero intercept (blue) approaches the slope of the line (golden) as x increases.

Large commented ref section moved here

[edit]

I'm moving this here for page size/visibility reasons... Hiding old reference section. Needs to be checked, but everything should be in footnotes now, and in a much more verifiable format.

Some more citations to be added to this page

[edit]

Observing the articles below, it is safe to note that "High-Functioning Autism" can be a misclass of Developmental Psychosis.

This distinction of course is related to https://en.wikipedia.org/wiki/Imprinted_brain_hypothesis and https://en.wikipedia.org/wiki/Talk:Imprinted_brain_hypothesis

[edit]

Observing the hypothesis, one can claim that gender non-conformity, "deviance", left-handedness, intelligence, reading disabilities, and higher digit ratios.

I am taking a note here that there are scientific articles that shows the link between digit ratio and sport. We need to add to this article. 60.242.13.83 (talk) 22:23, 24 November 2023 (UTC)[reply]
