Why we can't trust academic journals to tell the scientific truth
Academic journals don’t select the research they publish on scientific rigour alone. So why aren’t academics taking to the streets about this?

by Julian Kirchherr, Assistant professor at the faculty of geosciences, Utrecht University, the Netherlands (keyword scholar: Energy infrastructure environment development sustainability).

" These high-impact journals demand novel and surprising results. Unsuccessful replications are generally considered dull, even though they make important contributions to scientific understanding. Indeed, 44% of scientists (https://journals.plos.org/plosone/article/file?id=10.1371/journal.pone.0005738&type=printable) who carried out an unsuccessful replication are unable to publish it. I have personal experience of this: my unsuccessful replication of a highly cited study has just been rejected by a high-impact journal. ..."  Il fatto che le pubblicazioni siano legate alla carriera ha un risultato. I ricercatori cercano di pubblicare su riviste ad alto impact factor. E per pubblicare "Fourteen per cent of scientists claim to know a scientist who has fabricated entire datasets, and 72% say they know one who has indulged in other questionable research practices such as dropping selected data points to sharpen their results."

I giornali di cui si parla sono giornali peer-reviewed. Gli articoli sono sottoposti ad un processo di revisione. Il problema sollevato da Julian è il seguente. Ha provato a replicare uno studio molto citato e non c'è riuscito; non è però riuscito a veder pubblicati i suoi risultati. Ma a monte c'è il problema che uno studio è stato pubblicato, anche se ha qualcosa che non funziona.
