I assume that when studies in which a participant has to choose between two things what item is on the left and right is controlled for. But I was curious, with all things being equal is their a bias on what someone will choose? Something on the right or left? Has this even been studied? If so how strong is it? I would guess it would coincided with handiness.

A study in 2011 was done on the subject using abstract "good" or "bad" and found that there was a preference and that it was closely related to motor fluency. The cool thing found in that study is that the bias can be reversed with a short term handicap before the survey in the form of a ski glove on their dominant hand while they to set up dominoes.
