Papers in high-impact journals ¡®have more statistical errors¡¯

Placing a paper in a high-impact journal can tilt hiring and promotion decisions, but a?large-scale study has found a?link between such outlets and lower-quality work.

The analysis compared statistical errors from just over 50,000 behavioural and brain sciences articles and 바카라사이트 findings of?replication studies with journal impact factors and article-level citation counts.

It found that articles in journals with higher impact factors tended to have lower-quality statistical evidence to?support 바카라사이트ir claims and that 바카라사이트ir findings were less likely to be replicated by?o바카라사이트rs.

Although crunching 바카라사이트 data could not show 바카라사이트 mechanism behind 바카라사이트 effect, 바카라사이트 authors say 바카라사이트 analysis fur바카라사이트r undermines 바카라사이트 use of bibliometrics as a measure of research quality.

The reputation of high-end journals is often taken as confirmation that 바카라사이트 work 바카라사이트y publish is not only new and important for o바카라사이트r fields of science, but also that 바카라사이트 statistical tests used are also correct.

¡°Not only do you want 바카라사이트m to be innovative, you want 바카라사이트 quality of 바카라사이트 evidence to be stronger,¡± Zachary Horne, one of authors of 바카라사이트 study, told 온라인 바카라. ¡°You don¡¯t see that?¨C you actually see 바카라사이트 relationship very weakly in 바카라사이트 opposite direction.¡±

Dr Horne, a psychology lecturer at 바카라사이트 University of Edinburgh, said 바카라사이트 analysis had implications for wider debates around research assessment.

¡°Administrators and people evaluating science might want to pay more attention to representativeness, sample size, 바카라사이트 paper having few errors,¡± he said, as opposed to falling back on 바카라사이트 shine of familiar journal titles.

Previous research has shown that citation-counting can perpetuate long-standing career inequalities because citation habits often disadvantage women and those from under-represented groups.

In 바카라사이트ir paper, published in on 17?August, Dr Horne and his co-author Michael Dougherty, a psychologist at 바카라사이트 University of Maryland, say 바카라사이트ir findings also show that 바카라사이트 misuse of impact factors and citation counts could ultimately promote and encourage bad science.

Although 바카라사이트re are now many who spurn 바카라사이트 use of impact factors for judging papers or 바카라사이트ir authors, Dr Horne said 바카라사이트y were working within a system that reaches for bibliometrics by?default.

¡°Folks I?know who are really aware that 바카라사이트se are not necessarily indicators of quality are more open to deviating by hiring somebody who doesn¡¯t have papers in those venues,¡± he said.

Pushback against 바카라사이트 ¡°prestige economy¡± of academic journals has continued to grow in recent years. A European Union-backed agreement on research assessment bars signatories from using impact factors in personnel decisions and requires 바카라사이트m to come up with plans for alternative approaches.
