Uh, huh. I've seen more rigor applied to a Gallup poll.
Researchers studied 46 people. In Nebraska. By showing them pictures of bunny rabbits & snakes, etc. Then sat back and measured their reactions - like skin conductivity and eye blinking.

The 535 members of congress & their voting record would be a much better sample group for fearful eye blinking.
