Vetenskaplig framgång genom att citera sig själv

Hur ofta har man inte irriterat sig på forskare som mest citerar sig själva i sina artiklar? Det visar sig att dessa beter sig rationellt, om det är vetenskaplig framgång de är ute efter. Detta enligt en ny studie av James Fowler och Dag Aksnes (publicerad i Scientometrics, 2007, 72(3): 427–437). Abstract:

Self-citations – those where authors cite their own works – account for a significant portion of all citations. These self-references may result from the cumulative nature of individual research, the need for personal gratification, or the value of self-citation as a rhetorical and tactical tool in the struggle for visibility and scientific authority. In this article we examine the incentives that underlie self-citation by studying how authors’ references to their own works affect the citations they receive from others. We report the results of a macro study of more than half a million citations to articles by Norwegian scientists that appeared in the Science Citation Index. We show that the more one cites oneself the more one is cited by other scholars. Controlling for numerous sources of variation in cumulative citations from others, our models suggest that each additional self-citation increases the number of citations from others by about one after one year, and by about three after five years. Moreover, there is no significant penalty for the most frequent selfciters – the effect of self-citation remains positive even for very high rates of self-citation. These results carry important policy implications for the use of citations to evaluate performance and distribute resources in science and they represent new information on the role and impact of selfcitations in scientific communication.”

At the individual level there is large variability: extreme self-citers and persons who hardly or never cite themselves. For example, one person had published 26 papers and self-cited these papers 132 times while receiving only 20 citations from others. At the other end, one person had published 45 papers and self-cited these papers 17 times while receiving 1517 citations from others.”
