You think back to a decision you made, and because it didn't work out, you assume it was the wrong one. In the scientific community, this is called HARKing, which stands for "Hypothesis After Results Known," and I do it all the time, possibly even in a recent story about a shot selection from off the green. Although the course strategy expert Scott Fawcett agreed I chose poorly (re-created below), he cautioned against drawing broad conclusions based on one result. "Your up-and-down rate on this one is maybe 50-50," Fawcett said. "So you missed a coin flip and now you're judging the decision."
