Hindsight bias: Psychology instructor, heal thyself

Blog Post created by Sue Frantz on Jan 9, 2016

More than one Intro Psych textbook opens with this warning to students: Beware the hindsight bias! And students should beware, of course. Once the findings of a research study are revealed, it is hard for students to turn back the clock to the time when they did not know the results. With the results known, they are likely to label them as obvious; they knew them all along.

 

Steven Pinker (2016) urges us, as instructors, to remember that we, too, fall victim to hindsight bias, the curse of knowledge. We have spent years talking about these Intro Psych concepts. Because we have a difficult time imagining what it was like to not know these concepts, we may rush through our lectures, thinking our students either already know the concepts or can grasp them with quick, concise explanations.

 

How can we, as instructors, keep hindsight bias at bay in the classroom? Pinker says “[t]he best antidote is feedback: Asking students questions; monitoring their reactions, soliciting commentary; querying knowledge through regular assessments.”

 

On the first day of class, as I am explaining the structure of the course, I will explain to my students what the hindsight bias is, how I can’t remember what it was like to not know the content of this course, and how I have built a course designed to keep me informed of what they, the students, are understanding and what they are not as we go, before we get to the high stakes exams. And that I am going to trust them to tell me when they are not following what I am saying.

 

What better way to help students understand a concept like hindsight bias than to immediately use it to explain a common instructor behavior? With the added bonus of showing students how psychology can be used to teach psychology!
