November 28, 2009 from the Globe and Mail – “Bob is in a bar, looking at Susan, who is looking at Pablo. Bob is married. Pablo is not. Is a married person looking at an unmarried person?
c) Cannot be determined
Most people get the problem wrong because they tend to be “cognitive misers” – they put as little mental effort as possible into solving a problem… they quickly jump to a conclusion… If Susan is married, then a married person is looking at an unmarried person (Pablo). If she is single, then Bob, a married guy, is looking at an unwed woman. Either way, the answer to the question is yes…”
180 View – Let’s not be “cognitive misers” when it comes to things that matter.
