A fas­ci­nat­ing new study, Tver­sky and Kahneman’s Cog­ni­tive Illu­sions: Who Can Solve Them, and Why?, probes into the cog­ni­tive “heuris­tics and bias­es” researched by Daniel Kah­ne­man and Amos Tver­sky since the late 1960s.

If you have nev­er encoun­tered the “Lin­da brain teas­er” before, please give it a try:

Lin­da is 31 years old, sin­gle, out­spo­ken, and very bright. She majored in phi­los­o­phy. As a stu­dent, she was deeply con­cerned with issues of dis­crim­i­na­tion and social jus­tice, and also par­tic­i­pat­ed in anti-nuclear demonstrations.

Which state­ment is more probable?

(a) Lin­da is a bank teller.

(b) Lin­da is a bank teller and is active in the fem­i­nist movement.
