When Will Ferrel describes his George W Bush impression, he says he just imagines having a lot of “unearned confidence.” How would you know if you were one of these people? I first heard about the Dunning-Kruger effect in a comment on Hacker News and it immediately made me question a lot of things.
The Dunning?Kruger effect is a cognitive bias in which an unskilled person makes poor decisions and reaches erroneous conclusions, but their incompetence denies them the metacognitive ability to realize their mistakes
Throughout my life I’ve forced myself to be confident in my abilities (ie. gotten out of my comfort zone) in an effort to improve my skills and do more things. I’ve always considered being optimistic and determined to succeed was a positive thing.
Luckily, according to Dunning and Kruger if I suffered from this effect I wouldn’t be able to recognize and change anyway. WIN.
The Large Hadron Collider (LHC) is a particle accelerator complex intended to collide opposing beams of 7 TeVprotons. Its main purpose is to explore the validity and limitations of the standard model, the current theoretical picture for particle physics. This model is known to break down at a certain high energy level.
My brother swears he can get Chicago’s ESPN Radio 1000AM in and around Philly at night. I was skeptical, but then I looked it up on Wikipedia:
Medium wave and short wave radio signals act differently during daytime and nighttime. During the day, AM signals travel by groundwave, diffracting around the curve of the earth over a distance up to a few hundred miles (or kilometers) from the signal transmitter. However, after sunset, changes in the ionosphere cause AM signals to travel by skywave, enabling AM radio stations to be heard much farther from their point of origin than is normal during the day.
