Matthew effect

The Matthew effect of accumulated advantage, described in sociology, is a phenomenon sometimes summarized by the adage that "the rich get richer and the poor get poorer." The concept is applicable to matters of fame or status, but may also be applied literally to cumulative advantage of economic capital.

The term was coined by sociologist Robert K. Merton in 1968 and takes its name from the parable of the talents in the biblical Gospel of Matthew. Merton credited his collaborator and second wife, sociologist Harriet Zuckerman, as co-author of the concept of the Matthew effect.

The concept is in two of the Parables of Jesus in the synoptic Gospels (Table 2, of the Eusebian Canons).

The concept concludes both synoptic versions of the parable of the talents:

For unto every one that hath shall be given, and he shall have abundance: but from him that hath not shall be taken even that which he hath.

For I say unto you, That unto every one which hath shall be given; and from him that hath not, even that he hath shall be taken away from him.

The concept concludes two of the three synoptic versions the parable of the Lamp under a bushel (absent in the version of Matthew):

For he that hath, to him shall be given: and he that hath not, from him shall be taken even that which he hath.

Take heed therefore how ye hear: for whosoever hath, to him shall be given; and whosoever hath not, from him shall be taken even that which he seemeth to have.

The concept is presented again in Matthew outside of a parable during an explanation of the purpose of parables:

For whosoever hath, to him shall be given, and he shall have more abundance: but whosoever hath not, from him shall be taken away even that he hath.

In the sociology of science, "Matthew effect" was a term coined by Robert K. Merton to describe how, among other things, eminent scientists will often get more credit than a comparatively unknown researcher, even if their work is similar; it also means that credit will usually be given to researchers who are already famous. For example, a prize will almost always be awarded to the most senior researcher involved in a project, even if all the work was done by a graduate student. This was later formulated by Stephen Stigler as Stigler's law of eponymy — "No scientific discovery is named after its original discoverer" — with Stigler explicitly naming Merton as the true discoverer, making his "law" an example of itself.
