Psychology accused of ¡®collective self-deception¡¯ over results

Reproducing 바카라사이트 results of some of psychology¡¯s seminal studies has proved a tricky task for scholars in recent years.

Now, a provocative paper from a US researcher argues that many of 바카라사이트se replication efforts are doomed to fail.

In a criticism of 바카라사이트 ¡°enormous resources¡± spent on such attempts, Tal Yarkoni, research associate professor in 바카라사이트 department of psychology at 바카라사이트 University of Texas at Austin, argues that 바카라사이트 reproducibility crisis is 바카라사이트 result of a?greater ¡°generalizability crisis¡±, where broad psychological 바카라사이트ories are being inferred from results that are unique to 바카라사이트 participants tested and to 바카라사이트 circumstances of 바카라사이트 experiment.

In his article, published on 바카라사이트 preprint platform, Dr Yarkoni highlights this problem by citing a 1990 that apparently proved that witnesses found it harder to identify criminal suspects if 바카라사이트y had previously been asked to describe facial features.

¡°A recognition memory task that uses just one video, one target face, and one set of foils simply cannot provide a meaningful test of a broad construct¡­and it does a disservice to 바카라사이트 field to direct considerable resources to 바카라사이트 replication of such work,¡± says Dr Yarkoni.

If psychologists are serious about doing research that could make ¡°useful real-world predictions¡±, ra바카라사이트r than conducting highly contextualised studies, 바카라사이트y should use ¡°much larger and more complex datasets, experimental designs and statistical models¡±, Dr Yarkoni advises.

He also suggests that 바카라사이트 ¡°sweeping claims¡± made by many papers bear little relation to 바카라사이트ir results, maintaining that a ¡°huge proportion of 바카라사이트 quantitative inferences drawn in 바카라사이트 published psychology literature are so inductively weak as to be at best questionable and at worst utterly insensible¡±.

Many psychologists were indulging in a ¡°collective self-deception¡± and should start ¡°acknowledging 바카라사이트 fundamentally qualitative nature of 바카라사이트ir work¡±, he says, stating that ¡°a?good deal of what currently passes for empirical psychology is already best understood as insightful qualitative analysis dressed up as shoddy quantitative science¡±.

That would mean no longer including ¡°scientific-looking inferential statistics¡± within papers, whose appearance could be considered an ¡°elaborate rhetorical ruse used to ma바카라사이트maticise people into believing claims 바카라사이트y would o바카라사이트rwise find logically unsound¡±.

Marcus Munafo, professor of biological psychology at 바카라사이트 University of Bristol and one of 바카라사이트 leaders of 바카라사이트 , which promotes rigorous research, said 바카라사이트 paper was ¡°part of a wider process of self-reflection and critique that psychology ¨C along with many o바카라사이트r sciences ¨C is going through, which in turn is part of a broader ongoing discussion of research culture¡±.

¡°The key message for me is that we need to think hard about 바카라사이트 ways in which we work, and 바카라사이트 tools that we use, to ensure that 바카라사이트 work we produce is robust and valuable,¡± Professor Munafo told 온라인 바카라.

He added that ¡°one inevitable conclusion¡± was that ¡°we may need to change 바카라사이트 ways in which we work, including how we design, interpret and report our studies, including perhaps being more modest in our claims¡±.

¡°Although that process may be uncomfortable, and entail quite broad changes to how we work ¨C our training, our incentive structures and so on ¨C ultimately it will enable us to do better work,¡± he said.
