The psychological effect is "tendency towards the mean", and in this case, the mid-point isn't the mean.
Forcing individuals to choose a score above or below the mean yields a better sampling of the true distribution in this case.

- tiglionabbit 9y agoPerhaps people don't differentiate between 1-7 and 0-7 and assume that 3.5 is always going to be the midpoint?
