I don't think that's generally true though.

Ad companies run experiments on us all the time. When they A/B test across different groups of consumers to see the effectiveness of an ad, they are running a psychological experiment on us without our consent (asking, "how will exposure to this ad affect a person's likelihood of buying our product?").

I think the rules that you're referring to are for federally funded research only. But there's a large body of commercial research that is constantly experimenting on us without our consent.
