I think one of the biggest problems with the ADHD hunter theory is the jump from "some ADHD-traits being beneficial in some circumstances", to "ADHD evolved, because it made us better hunters."

There's a bunch of interesting studies that I tried to work through in a video essay.

In one 2024 study, 457 adults had to collect resources from patches that slowly depleted. People screening positive for ADHD left the patches earlier and actually achieved a higher reward rate. Another study found that children with more ADHD traits explored more during search tasks, and on one semantic-search task they performed better.

So under some conditions, what we describe as distractibility or switching can behave more like useful exploration (or at least that's how the study has been read).

Another study specifically created a task where ADHD traits were expected to help. Children had one minute to search an unfamiliar room for hidden coins. There was basically no advantage...

The genetic argument has a similar problem. The DRD4-7R variant famously showed different associations with nutritional status in nomadic vs settled Ariaal men, which looks very compatible with an environment × genotype effect. But DRD4-7R isn't an “ADHD gene”, ADHD is highly polygenic, and a later study didn't replicate the nutritional result in a comparable group.

The part I find strangest is how little direct evidence there actually is for the central claim. A 2016 systematic review looking specifically for empirical tests of evolutionary explanations of ADHD started with 790 records and found only three eligible studies. And even those didn't really test the core ADHD phenotype... So we pretty much don't have the data.

I absolutely think environment matters. But from what I see in the evidence, the whole ADHD=Hunter-Brain thinking is WAY further than the evidence is.

I went through the studies in more detail here because this got way too long for a reddit post: [https://youtu.be/5JP6Ez1eV2o](https://youtu.be/5JP6Ez1eV2o)

But I'm curious what everyone else thinks? Do you believe in this theory? Why/ why not?

Also here's the literature I worked through if you want to nerd around like me:

The "ADHD hunter theory" makes much bigger claims than the evidence supports!
