[[Personal Science (book)]] recommends simpler scales to stop user from wasting time on details. I recommend somewhat wider scales that split positive and negative into 'definitely' and 'extremely/unusually' and the neutral state into two to let user guess which side is more likely.

Ratings '''drift''' is when user adjusts to some new average over time and that average becomes their new neutral. Sometimes this is caused by user not being to set in the ways they measure the phenomenon and exactly what ratings mean what. This is a problem because it creates false positives for tests and makes comparing between long time periods difficult. It is possible, but not recommended, to look at distribution, especially extremes, and guess at how ratings may have drifted.
