FAA seeking cognitive testing volunteers:
 

Yeah this doesn't sound like a trap at all...


"Pilots attending EAA AirVenture 2024 in Oshkosh, Wisconsin, could offset some of their expenses by participating in a paid FAA research study. The agency is offering prepaid gift cards valued at between $300 and $500, depending on current medical privileges at the time of the study. Participants must have logged flight or simulator time within the previous six months."

I wouldn't do it if you have any concerns about your own cog function.

Would I do it for $500? Yup, if it took less than an hour.

I did it as part of another paid study with the Feds. It's all anonymized and you sign paperwork stating as much. Nothing can be used against you, even if you completely fail. If you want to quit halfway through the study, you get paid for it still. It's with the CAMI research people.
I found it interesting and they will give you your results on how you compare with the study group and with other study groups. All in it took around 2 hours. The purpose of the study is to update their cog screening tests, which haven't changed in decades. They need a baseline of pilots holding various qualifications and medical certificates.
They are all about the data. Your name won't go any further than the study room.
