Studies

"Studies have found..."

that many studies are inaccurate
that I lose
that the last ice age was caused by too little pollution
that mechanical pencils break more than ordinary pencils
that 100% of the people surveyed believe that cats are superior beings (n = 1)
that 87% of people surveyed know the game where the object is to forget the game
that 2% 100% of the people in this room lose said game
that 100% of the people surveyed agreed to take our survey
that 68% of made-up statistics are about the prevalence of made-up statistics

showing that all studies are wrong
how many people are in some minority group? (is it a majority?)
how many sneeze because of sun?
effectiveness of handwriting vs. typing
Dvorak vs. QWERTY
emacs vs. vim
monkeys + typewriters
How many humans are intelligent?
Find a way to give tests of animal intelligence to humans without the bias of being able to communicate easily with the participants. Are there any that show that humans are not the most intelligent species of animal?
How much does religious tolerance or lack thereof correlate with which religion a person belongs to; specifically, where are atheists? (And are there any religiously-intolerant agnostics?)
What effect do attempts to debunk pseudoscience actually have? (And have claims about how bad pseudoscience is actually been scientifically tested?)
A study showing that (at least in some particular circumstance) intuition works better than logic
