From No Limit Hold 'em: Theory and Practice by David Sklansky and Ed Miller.
Concept No. 49: If someone makes a big bet into multiple players, typically he will have a good, but not great, hand.
This is very similar to concept 35, and once again, I don't have anything very insightful to say. I think the claim made by this concept is usually true, but it's not very reliable. Different people play differently at different times.
