Ever since I realized the average IQ of the average human (and other species), I feel like I've been playing farmville with life

Attempts to measure IQ are problematic for several reasons and even the best tests are a crude estimate of whatever we are measuring that some tester believes is a marker for intelligence. Nevertheless I agree with the sentiment that the intelligence of the "average" American human is a disappointment. My "evidence" is that about 32% of Americans support Trump and think he is doing a "great job" and are oblivious to facts or evidence to the contrary.

If they could make me less sensitive that would be great.

What is the average ?
