Tower of Babel bias
A popular term for a bias introduced in a meta-analysis, when only English-language studies are included in the data being analysed.
The Tower of Babel was a terraced pyramidal structure built in Babylon in Mesopotamia, which is described in Genesis 11:1-9; according to the Bible, Noah’s descendents settled in southern Mesopotamia after the Great Flood. When they built their city, they started to build a tower that would reach to heaven, which displeased God. God made the builders speak different languages; because they could not communicate, they stopped working and scattered over the earth.
