more on bird/human brains

Yeah, I'm intrigued too.  See BirdbrainsMax, a new version that actually acts like a bird, whereas the earlier BirdBrains2 actually acts like a human.  The difference is that the latter actually determines "empirical probabilities" for each alternative and uses these to determine its behavior.  The former doesn't determine "empirical probabilities" at all but instead uses the ratio of overall absolute successes for the two alternatives to probabilistically bias its behavior.  The upshot is being "less afraid of commitment to one answer"?
