Jamais Vu: The Familiar Seems New
Have you ever written a common word and momentarily questioned whether you spelled it correctly? If so, you might have experienced jamais vu. You’ll notice I wrote jamais vu, not the more common expression déjà vu. Déjà vu (French for “already seen”) is the feeling we’ve experienced something before when it’s actually new to us….
The Early Bird May Not Get The Worm
Despite the common saying, the early bird may not get the worm. The phrase ‘the early bird gets the worm’ suggests there is an advantage for doing something before anyone else. It’s so familiar that it’s often shortened to early bird; a term which can be used in the sense of getting up early (She’s…
Debunking the Dunning-Kruger Effect
It might be time to debunk the Dunning-Kruger effect. For those who may not be familiar, in the 1990s Cornell University professors David Dunning and Justin Kruger conducted a now-famous experiment to test whether incompetent people were unaware of their incompetence. In the study, the lowest-scoring participants estimated they did better than 62% of everyone else, while the highest-scoring…
Can Pistachios Help You Sleep?

Ever wonder why you seem to come up with your best ideas when you’re in the shower? Research titled ‘Inspired By Distraction’ claimed you become more creative in your problem solving when you’re doing simple tasks which allow your mind to wander. The authors wrote, “Compared with engaging in a demanding task, rest, or no…
Trust Your Fear Instinct
Most people spend their lives avoiding things that scare them but the key to self-protection might be to trust your fear instinct. Fear is a natural response to physical and emotional danger, based on an evolutionary survival mechanism. The physical response, known as “fight or flight,” includes sweating, increased heart rate, and high adrenaline levels…
The Art of Countersignaling
Not long after I wrote about humblebragging, a reader asked me if humblebragging was an example of countersignaling. My short answer is ‘no’ but it deserves a more nuanced explanation. Signaling is a biological concept in which information is implicitly conveyed to others. Red mushrooms signal to would-be predators that they are poisonous. Peacocks bare…
Negotiated Givers Might Be The Best Employees
While talent, hard work, and passion are important characteristics for high performance, business success is increasingly dependent on how employees interact with others. In a team environment, so-called negotiated givers might be the best employees. In the best-selling book, “Give and Take: A Revolutionary Approach to Success,” Wharton professor Adam Grant describes three different workplace…
