There is a ton of evidence of it. Some humans are up to 20-30% neanderthal. Professors just arent screaming it from the rooftops. See the most recent dwarkesh podcast

I think you’ve got your facts garbled, or the podcast has. Up to about 20% of Neanderthal DNA has survived somewhere dispersed among humans, but some countries and backgrounds have a maximum of 3% per human. The average is about 2% outside Africa.

watch the podcast again, he explicitly calls out:

"but some countries and backgrounds have a maximum of 3% per human. The average is about 2% outside Africa."

as mostly false

I would like to see his sources because that contradicts the most well known studies. There are still a lot of paleoanthropologists who don't think that interbreeding was possible at all and the apparent Neanderthal admixture in modern humans is due to contamination.

dont have time to find it. he basically says the 2% thing is an antiquated understanding that conflicts with recent ancient dna studies. Go watch the podcast

I can track down the studies he’s criticising. A Google search doesn’t show up anything refuting those. What are the studies he’s citing?

Watched it. He didn't present _any_ sources supporting his claims. There's nothing there.

Publishing a ton of research on this would basically be a career ending move

Ok, you're almost there. Why would it be career ending?

If there's a ton of evidence for this, please provide some citations. I for one have never heard a single scientific claim for individual people having 20-30% Neanderthal DNA. As the sibling comment said, there may be that much Neanderthal DNA spread around in total, but no single individual sapiens has more than a tenth of that.
