Excellent! As a clinical psychologist with much interest in neuroscience, I've had so many times to caution people about neurobabble (not the neuroscience itself, but taking the research far beyond what it actually is able to tell us - I tried to be evenhanded in my summary of mind body research here: I hope I didn't fall into any of the myths you mention! https://www.remembertobe.life/research

I actually clicked the link to see if you were going to flat-out declare hemispheric differences to be a myth.

I'd say, roughly, that 30 years of research reviewing 10s of 1000s of studies gives Dr. Iain McGilchrist the credibility to suggest there are ways of attending to the world that are roughly correlated with the different hemispheres (in virtually every presentation he gives, he begins by saying it is NOT true that the left hemisphere is logical and the right emotional; the left literal and the right creative; BOTH are involved with logic, BOTH with emotion, BOTH with creativity)

Note I said "roughly" correlated. McGilchrist himself is very careful to say this.

But I've been participating in an online forum with several dozen McGilchrist admirers over the past 9 months - and I seem to be the only one there cautioning, in every post, NOT to make the LH and RH into rigid entities.

Even if our minds work that way (they don't) we simply don't understand the brain enough to make such emphatic statements.

The observation that there are two major and quite different attention styles - one which divides the world into separate pieces, the other seeing the whole as greater than the sum of the parts - has been around for several thousand years.

it's helpful for those who think neuroscience is full of great wisdom to understand attention in terms of the brain, but it's urgent to take this understanding quite lightly, knowing that much of our understanding of the brain is likely to be radically different in just 50 years (or maybe even 25 years).
