Behavioral Biases, Runner’s High, and Star Wars
by Lauren Foster, CFA Insititute
Is it just me, or does it seem that hardly a week goes by without another study or article about diversity in the workplace making headlines?
I don’t have the answer, but it did make me wonder whether I was suffering from “frequency illusion” or “recency illusion,” also known as the Baader-Meinhof phenomenon.
“The what?” I hear you ask. “Wasn’t the Baader-Meinhof Gang an infamous radical guerrilla group?”
Yes, it was. And the Baader-Meinhof phenomenon is the term for when something you’ve just noticed, experienced, or been told about suddenly seems to pop up everywhere.
Of course, discovering that there was a term for this led me down the proverbial rabbit hole: Why would it be called the Baader-Meinhof phenomenon?
But first, some background: Back in 2006, Arnold Zwicky, a Stanford linguistics professor, minted the term “frequency illusion.” It is the result, he wrote, of two well-known psychological processes: selective attention and confirmation bias.
As explained in a 2013 article in the Pacific Standard, “Selective attention kicks in when you’re struck by a new word, thing, or idea; after that, you unconsciously keep an eye out for it, and as a result find it surprisingly often. The second process, confirmation bias, reassures you that each sighting is further proof of your impression that the thing has gained overnight omnipresence.”
Then, in 1994, a person commenting on the St. Paul Pioneer Press’ online discussion board dubbed the frequency illusion “the Baader-Meinhof phenomenon” after hearing two references to Baader-Meinhof within 24 hours.
So there you have it. The next time you happen upon a piece of information and soon afterwards encounter the same subject again and yet again, you’ll know what to call it.

And Now for Something Completely Different
- Ah, the “runner’s high.” Researchers recently discovered that “at least part of the euphoria that comes after a strenuous workout — runner’s high — is due to endocannabinoids, the body’s self-produced counterparts to some of marijuana’s mood-enhancing chemicals.” According to the article, “Getting ‘High’ On Your Own Supply,” “the finding overturned decades of conventional wisdom claiming that natural highs come from endorphins, the chemicals that became famous in the 1980s for their euphoric effects. While endorphins seem to help numb our muscles during a workout, their molecules are too large to cross the blood-brain barrier and trigger a ‘high’ like endocannabinoids can.” (Discover)
- Speaking of running, every Saturday morning I meet up with my regular group of running buddies, and whenever I turn on the radio, the BBC program The Conversation is always on air as I drive. Last week’s episode was a conversation between two opera singers. South African soprano Pretty Yende discovered opera by chance: She was 16 years old and watching a British Airways advertisement that featured the “Flower Duet,” from Lakme. I clearly remember the ad as I grew up in South Africa. If you’re curious about the power of a 1:31 minute ad to change the course of a life, take a look. (The Conversation, YouTube)
