In mathematical analysis, limit superior and limit inferior are important tools for studying sequences of real numbers.Since the supremum and infimum of an unbounded set of real numbers may not exist (the reals are not a complete lattice), it is convenient to consider sequences in the affinely extended real number system: we add the positive and negative infinities to the real line to give the ...
In social psychology, illusory superiority is a cognitive bias wherein people overestimate their own qualities and abilities compared to others. Illusory superiority is one of many positive illusions , relating to the self , that are evident in the study of intelligence , the effective performance of tasks and tests, and the possession of ...
In these limits, the infinitesimal change is often denoted or .If () is differentiable at , (+) = ′ ().This is the definition of the derivative.All differentiation rules can also be reframed as rules involving limits.
Limit inferior and limit superior are more general terms that represent the infimum and supremum (respectively) of all limit points of a set. The limit inferior and limit superior of a sequence (or a function) are specializations of this definition. Therefore, the limit inferior, limit superior, and limit all fail to exist at x=2 in the example.
Some researchers include a metacognitive component in their definition. In this view, the Dunning–Kruger effect is the thesis that those who are incompetent in a given area tend to be ignorant of their incompetence, i.e., they lack the metacognitive ability to become aware of their incompetence.
A superiority complex is a defense mechanism that develops over time to help a person cope with feelings of inferiority. [1] [2] The term was coined by Alfred Adler (1870–1937) in the early 1900s, as part of his school of individual psychology.

A limit situation (German: Grenzsituation) is any of certain situations in which a human being is said to have experiences that differ from those arising from ordinary situations. [ 1 ] The concept was developed by Karl Jaspers , who considered fright, guilt, finality and suffering as some of the key limit situations arising in everyday life.
