If it weren’t for the real estate market, my projection for GDP would have been accurate.” Which of the following is the best interpretation of McLaughlin’s statement, from a behavioral finance view? McLaughlin is using: A) an “if-only” defense for his inaccurate forecasts and his recognition of it will sharpen his abilities.
