Should citations be field-normalized in evaluative bibliometrics? An empirical analysis based on propensity score matching

作者:

Highlights:

• We investigated the question how strong fields influence citation counts of papers.

• Can field differences be traced back to factors possibly influencing citations (FICs)?

• We considered 13 variables as FICs, e.g., number of pages, co-authors, and cited references.

• We applied propensity score matching as statistical method to make causal statements.

• The results revealed that field differences did not completely vanish but were dramatically reduced.
