In this case, participants are asked to assess their performances in relation to the other participants, for example in the form of estimating the percentage of peers they outperformed. [17] [13] [2] The Dunning–Kruger effect is present in both cases, but tends to be significantly more pronounced when done in relative terms. This means that ...
The concept of "right-brained" or "left-brained" individuals is considered a widespread myth which oversimplifies the true nature of the brain's cerebral hemispheres (for a recent counter position, though, see below). Proof leading to the "mythbuster" of the left-/right-brained concept is increasing as more and more studies are brought to light.
The normal distribution, also called the Gaussian or the bell curve. It is ubiquitous in nature and statistics due to the central limit theorem: every variable that can be modelled as a sum of many small independent, identically distributed variables with finite mean and variance is approximately normal.
The term was coined by Richard Herrnstein and Charles Murray in their 1994 book The Bell Curve. [ 13 ] [ 14 ] [ 15 ] Flynn stated that, if asked, he would have named the effect after Read D. Tuddenham [ 16 ] who "was the first to present convincing evidence of massive gains on mental tests using a nationwide sample" [ 17 ] in a 1948 article.

The Gaussian function is the archetypal example of a bell shaped function. A bell-shaped function or simply 'bell curve' is a mathematical function having a characteristic "bell"-shaped curve. These functions are typically continuous or smooth, asymptotically approach zero for large negative/positive x, and have a single, unimodal maximum at ...
On the right side, the two squares look almost the same. The Weber–Fechner laws are two related scientific laws in the field of psychophysics , known as Weber's law and Fechner's law . Both relate to human perception, more specifically the relation between the actual change in a physical stimulus and the perceived change.
In statistics, an inverted bell curve is a term used loosely or metaphorically to refer to a bimodal distribution that falls to a trough between two peaks, rather than (as in a standard bell curve) rising to a single peak and then falling off on both sides.
