Not a fundamental issue but still of interest.
The second half of the talk is consistent with an honest form of HBD/race realism: we are NOT “all the same” and there is inter-population, as well as intra-population, physical differences that make certain people better suited for particular athletic endeavors.
The first half of the talk is entirely consistent with what I wrote here:
Fifth, although I’m not much interested in sports, the fact that reaction times have been slowing over the past century provides food for thought – thought indirectly linked to racial activism since the “bread and circuses” masses love sports, and thus sports, as part of mass pop culture, affects the race-culture problem.
I note there is a rough correlation between sociopolitical views and ideas about athletic performance over time. Those on the Left are more prone to “overrate the present” and lionize (mostly Colored) modern athletes as far superior to the (mostly White) athletes of the past. Those on the Right are less likely to casually dismiss the “traditional sports heroes” of the past.Now, if reaction times are really slowing, then what can we say about athletic performance in sports in which reaction time is important – hitting a baseball for example (or boxing or hockey)? It puts into question leftist assumptions rooted in jock sniffing the Negro athlete. The components of performance related to reaction time – fundamental for some sports – would seem to be declining, not improving, over time.Indeed, reaction times differ by race, with Negroes being the slowest, which again makes one question whether the Negro athlete of today is superior to the White athlete of the past (and, of course, intra-racial White-White cross-era comparisons of declining reaction time question leftist assumptions about sports as well). One can make counter-arguments that athletes do not represent the overall population, and that Victorian England was one specific sample, and that of course other factors than reaction time are important in athletic performance, etc. but still, the idea is provocative. The Caste Football pro-White sports types probably need to look into the implications of declining reaction times in making cross-era sports comparisons, implications favorable to a narrative of a Golden Age of White American sports.
It would seem that Sallis is right once again. A significant portion of the “vast improvement” in athletic performance over time is due to improved technology, training, nutrition, and drugs, not innate ability. As to that portion that may be innate, the second half of the talk, alluded to above, explains much - not an overall population improvement in innate ability, but better selection within population of outliers best suited for particular sports. For the most part though, it’s better technology and training masking degenerating reaction time and degenerating IQ (some sports require some degree of intelligence for optimal success).
