Experiential Inoculation

What Works to Build Mental Immunity - #10

In experiential inoculation¹, a teacher intentionally deceives their students and then provides a debriefing to help them learn how to identify misleading techniques. A demonstration that imparts the experience of being fooled can spark humility, curiosity, and a desire to learn, much like a magic trick. How did the trick work? Why did it fool us? What vulnerabilities did it exploit?

Applications

• Find or create a false narrative about a topic of focus. Present it to your students at face value and notice if any of them seem skeptical about it. If so, ask them why and lead toward a debriefing.  If not, eventually pivot toward revealing the flaws in the narrative.

• Use the Barnum Effect:² Have students do a short personality test. Later, distribute fake “personality results” constructed from astrology readings. Pretend these are individualized, but give everyone the same thing. Ask the class if they found the reading relatable. By a method of our choosing, reveal to them that they were all given the same result. This demonstration was first performed by Bertram Forer in 1949.³

Notes

Experiential Inoculation is a new concept⁴ and has not yet been extensively researched, however, ample research on psychological inoculation⁵ suggests that this approach should be useful. In English, Social Sciences, and Psychology classes, you can use experiential inoculation to introduce lessons on rhetoric, persuasion, and manipulation. In science classes, you can use it to introduce lessons on scientific methods and evidence-based reasoning. Whatever the case, it’s crucial that you thoroughly debrief. Make clear that your attempt to fool them was only to produce a teachable scenario and emphasize the importance of responsible communication. In any case, try to keep these lighthearted or even funny.
