Out of curiosity does anyone have a psychology degree? I have a minor and remember some of the stuff of memory bias with recency and what not.
My personal preference is that every judge approaches every single performance as an individual event. That team should be able to get the same score whether they compete alone or in a row of 300 teams at the beginning or the end. If the same score cannot be achieved each time a team performs (meaning they do the EXACT same performance) then it must be looked at what is changing each time and how to make that more consistent.
Degree in psych, + most of the credits for one in math - but that was a long time ago. (This is all a semi-educated guess, as the EPs don't release enough information to get a real handle on things.)
There are several types of memory biases that could come into play, but I would guess that they are a very small portion of the error/variance in scoring. (It would also be noted that memory of previous routines would not always make a score go up.)
The errors that most concern me are:
1. The (mostly) random error caused by which part of the floor a judge happens to be watching.
2. Judges adjusting their range based on personal preference of styles.
3. The idea that more consistent scoring (scores being closer together) somehow demonstrates accuracy.
4. The idea that throwing out the high and low score adds to accuracy.
5. Judges not using the entire range given - which effectively throws off the weighting system.
6. (The biggest one) Simple arithmetic / data entry errors.
