Spørgsmålsformuleringens betydning for opbakningen til en afskaffelse af forsvarsforbeholdet #2
På Politologi.dk har jeg som bekendt lavet en oversigt, hvor man kan følge de seneste meningsmålinger foretaget i forhold til folkeafstemningen om forsvarsforbeholdet. Ideen var, at det – ligesom med folketingsvalg og kommunalvalg – ville være godt at have ét sted hurtigt at kunne se, hvad de seneste målinger viser. Da jeg lavede den første […]
Horse race coverage of elections
The other day I talked to The Journalists’s Resource about how journalists should cover opinion polls. Subsequently, the journalist wrote a great article with a list of things to avoid as a journalist when covering opinion polls – and what to do (it is a constructive piece of journalism). You can read the article here. […]
Experiments and societal challenges
The randomised controlled trial is seen as the gold standard within the social sciences. I do not disagree. I love well-executed experiments with strong causal identification. If two studies, one experimental and one non-experimental, differ in their conclusions, there is no doubt which study I, all else equal, will side with. Most importantly, I often […]
Spørgsmålsformuleringens betydning for opbakningen til en afskaffelse af forsvarsforbeholdet
Vi er nu en måned fra folkeafstemning om forsvarsforbeholdet. I løbet af de seneste uger har debatten omkring folkeafstemningen især beskæftiget sig med, hvilket spørgsmål, vælgerne skal forholde sig til. Skulle spørgsmålet handle om at deltage i det europæiske samarbejde om sikkerhed og forsvar? Eller skulle forsvarsforbeholdet nævnes eksplicit? Der har i den forbindelse været […]

70% of meetings keep employees from doing productive work
How can we measure whether a meeting is productive or not? And if we can, what is the percentage of meetings that keep employees from doing productive work? 10%? 15%? 80%? Did you know that 70% of meetings keep employees from doing productive work? Boro baba. In this post I will show that there is […]
Keynote on opinion polls
I recently gave a keynote speech at the conference Sondagens: da Conceção ao Impacto. Luckily, I could give the talk in English (and not Portuguese). Alas, it had to be online. The title of my talk was ‘Opinion polls are bad and we need more of them’. As the English translation of the conference title […]
Kvalitetsvægtede gennemsnit af meningsmålinger og statistisk usikkerhed #4
I mit forrige indlæg om kvalitetsvægtede gennemsnit af meningsmålinger og statistisk usikkerhed pointerede jeg, at der skal træffes flere valg, når man udarbejder et kvalitetsvægtet gennemsnit. En af implikationerne af dette er, at de forskellige vægtede gennemsnit ikke nødvendigvis vil vise de samme resultater. De forskellige vægtede snit inkluderer eksempelvis forskellige meningsmålinger. Det er herunder […]
