My response to Jezebel Lee's reply to my post at 9:55pm:
"“HoW dO yOu KnOw?” I know because I obsessively looked into the science behind tickling as a teenager, long before I was old enough to start engaging with the community. There hasn’t be a
lot of research, but there’s literally no evidence whatsoever that ticklishness varies between ethnicity. At all."
MY RESPONSE: You saying you looked into the science, without citing the science, is unpersuasive. If there are studies analyzing whether ticklishness is or is not correlated with ethnicity or gender, please quote them! If there are not, then the absence of any evidence does not suggest that there is no correlation. I expect that there are not, in line with your comment that there hasn't been a lot of research. As a society, we are skittish about looking at race/ethnicity, so there is not much research."
"Strictly speaking there are two types of ticklishness: knismesis and gargalesis. The most common accepted theories are that knismesis evolved to keep us away from bugs, and gargalesis evolved to train youngsters for combat. This evolved across the whole-ass human species. Why would ethnicity play a part? These other features such as lung capacity are dependant on things like environment and climate."
MY RESPONSE: There are plenty of differences based on ethnicity or gender where we don't know why. I think that is because typically, if any researcher want to research such differences, there is a societal anger at touching the subject. Here is an interesting article that at one point asserts that girls do better than boys in all subjects, when accounting for other variables.

We could have fun, if we are nonjudgmental, at speculating why this would be.
I've seen the arguments about bugs and combat, and personally didn't find those to be persuasive. But if I let my mind roam, I'd wonder whether people living in warmer climates where there are more bugs would be more knismesis-susceptible
"I don’t care if it’s “fun to speculate”; it’s harmful when people allow their “preferences” to develop into straight up racism, especially when it’s not based on any actual facts.
I’m 100% sure people will attack me for saying this but FFS I’ve had enough."
MY RESPONSE: It is not "straight up racism" to wonder whether one group of people is more ticklish than another. Accusing people of being racist for making such a suggestion is the problem I mention earlier. Do you think that the author of the article I cite above is straight up sexist for arguing that girls do better than boys on average? Perhaps you do. I do not. And I'm not attacking you for saying that, but I am saying I disagree.
