Confirmation bias.
After a quick skim of this study I don't feel it proof of anything. It looks more like p-hacking.
The data was pulled from a database so it's entirely statically analysis. There's no control. It's all self reported.
It's quite odd that being a former smoker caused one to perform better than a current smoker or a never smoker. Of course they leave that out of the abstract.
It's similar to confirmation bias, but I think that's the wrong name for the phenomenon. Confirmation bias is when we don't question things that align with our world view and reject things that don't align with it. It's certainly related to a desire for a sense of superiority, but there is something about that specific rush of neurotransmitters.
