complementarity hypothesis The literature on small-group formation contains two major hypotheses about the determinants of attraction between individuals. The second hypothesis maintains that interpersonal attraction takes place on the grounds of complementarity of characteristics between individuals.

The thought experiment proposed by Einstein, Podolsky and Rosen involved producing two particles and sending them far apart.

The similarity hypothesis suggests that individuals with ASD characteristics can help people with ASD. Individuals with ASD can support others with ASD based on empathy toward similar others.

The proposition that people tend to be attracted to others who have complementary needs to their own, a person with a high need for dominance, for example, being attracted to a person with a high need for submission, and vice versa.

The complement of the null hypothesis is called the alternative hypothesis. The null hypothesis is typically abbreviated as H0 and the alternative hypothesis as H1. Since the two are complementary (i.e. H0 is true if and only if H1 is false), it is sufficient to define the null hypothesis.

Reciprocity of liking (also called reciprocity of attraction or reciprocal liking) is a particular type of reciprocity that refers to the tendency for people to like others who express lik- ing for them. Reciprocity of liking is a key prin- ciple of attraction; at times, it has even been called a cultural truism.

The matching hypothesis (also known as the matching phenomenon) argues that people are more likely to form and succeed in a committed relationship with someone who is equally socially desirable, typically in the form of physical attraction.

It refers to how well two people fit together (complement one another) and meet each other’s needs. For example, young women may feel attracted to older men who have more economic resources and can provide for them.

In physics, complementarity is a conceptual aspect of quantum mechanics that Niels Bohr regarded as an essential feature of the theory. The complementarity principle holds that objects have certain pairs of complementary properties which cannot all be observed or measured simultaneously.

Examples of complementarity within research projects would be to include both in vivo and in vitro effects of a drug, or to compare both rat and mouse responses to a particular manipulation.

Complementarity was a central feature of Bohr’s reply to the EPR paradox, an attempt by Albert Einstein, Boris Podolsky and Nathan Rosen to argue that quantum particles must have position and momentum even without being measured and so quantum mechanics must be an incomplete theory.

Niels Bohr apparently conceived of the principle of complementarity during a skiing vacation in Norway in February and March 1927, during which he received a letter from Werner Heisenberg regarding an as-yet-unpublished result, a thought experiment about a microscope using gamma rays.
