Language decline as model for decline in religious affiliation

A report about the decline in religious affiliation, Religion may become extinct in nine nations, study says, compares that decline to the decline in use of lesser-spoken languages.

One of the team, Daniel Abrams of Northwestern University, put forth a similar model in 2003 to put a numerical basis behind the decline of lesser-spoken world languages.

At its heart is the competition between speakers of different languages, and the "utility" of speaking one instead of another.

"The idea is pretty simple," said Richard Wiener of the Research Corporation for Science Advancement, and the University of Arizona.

"It posits that social groups that have more members are going to be more attractive to join, and it posits that social groups have a social status or utility.

"For example in languages, there can be greater utility or status in speaking Spanish instead of [the dying language] Quechuan in Peru, and similarly there's some kind of status or utility in being a member of a religion or not."
