In November, a survey was published which found that 80% of Dutch youth with a Turkish background would not have a problem with the use of violence in jihad and 90% would think that Dutch Muslims who fight in Syria are heroes.
While some were shocked by the findings, others expressed doubts about the methodology of the survey or simply thought the results were improbable. Among other things, the survey was not based on a random sample and non-response wasn’t reported. The researchers did try to recruit a sample that was representative of the wider population on a number of background variables through quota sampling (discussions in Dutch here, here and here; research method here).
A Motivaction spokesperson said the way in which the research had been done was «acceptable» from a social sciences perspective.
Now a group of Turkish organisations demands that Minister Lodewijk Asscher, who contracted the survey, order Motivaction to release all results so they can ask an independent expert to review the study. If necessary, they may go to court to get the data.
I don’t know how likely it is the organisations will get the original data and if they do, it may still be difficult to demonstrate sampling bias. Still, if this is a step towards introducing principles of reproducible research in contracted policy research, then that’s an interesting development.
