You do make a good point tbh, there should definitely be more research into it; and you we could literally do it for free take a few people, give them an object to identify at a certain range and test sober against low dose of shooms...
I don't necessarily disagree and I'm not saying it's beyond the realm of possibility but context is missing. McKenna essentially put it out as fact that "increased visual acuity" is a definite result of ingestion and in a way that is evolutionarily beneficial. Fischer's paper just does not back this up. Seriously, how many people who make this claim have ever read the paper? Or critiques of McKenna's claims based on the paper? I know which side of 1% my guess falls on.
And I've never read that paper I just know the outlines of it, I'm gonna investigate xD
Tbh it's good to see someone who stands by their views and not falls into conformity
