Wenn Wissenschaftler etwas herausgefunden haben – wann kann man sich auch tatsächlich darauf verlassen? Eine Antwort lautet: Wenn Fachkollegen die Studie überprüft haben. Eine andere: Wenn sie in einer renommierten Fachzeitschrift veröffentlicht wurde. Doch manchmal reicht auch beides zusammen nicht aus, wie Forscher jetzt gezeigt haben. Und zwar auf die beste und aufwendigste Art: Sie haben die zugrundeliegenden Experimente wiederholt. Und geschaut, ob noch einmal dasselbe...

Jimmie Åkesson bekräftar vad vi länge anat När Jimmie Åkesson tidigare idag intervjuades av P3:s Morgonpasset inledde han med att såga hela kanalen. – Hade jag varit chef här hade jag lagt ner P3 direkt. Jag tycker det är vänsterliberal smörja, sade Åkesson. Att P3 är en skitkanal kan nog många av oss hålla med om. En massa tyckmyckentrutade ordbajsare som mellan ordkaskader spelar skvalmusik.

Few — if any — are less deserved than the macroeconomic theory/method — mostly connected with Nobel laureates Finn Kydland, Robert Lucas, Edward Prescott and Thomas Sargent — called calibration. In physics, it may possibly not be straining credulity too much to model processes as ergodic – where time and history do not really matter – but in social and historical...

Some common misunderstandings about randomization Randomization is an alternative when we do not know enough to control, but is generally inferior to good control when we do. We suspect that at least some of the popular and professional enthusiasm for RCTs, as well as the belief that they are precise by construction, comes from misunderstandings about … random or realized confounding on the one hand and confounding in expectation on the other … The RCT...

Modern economics — a severe case of model Platonism That is the great thing about abstraction. Working with what can be called ‘flex price’ models does not imply that you think price rigidity is unimportant, but instead that it can often be ignored if you want to focus on other processes. Simon Wren-Lewis When applying deductivist thinking to economics, mainstream economists like Wren-Lewis usually set up ‘as if’ models based on a set of tight axiomatic...
