That old SVO idea might not be so bad …

I have written about measuring a person’s Social Value Orientation (SVO) a couple times before (see here and here). In particular, Jeroen Weesie and I came up with a single question SVO measurement that we thought might be more efficient, includes an internal test of transitivity, and correlates with existing (much more tedious) measures. I […]

More social value orientation matters. The SVO slider measure

The Social Orientation Value (SVO) is a measurement of someone’s “social preferences”. Literally, it is meant to measure the extent to which you care about what others get. Often, It is measured through the “RING measure” (this involves 24 preference elicitations, see Liebrand 1984 or the details at the SVO page), or through a series […]

Beamer trouble: El Capitan and Powerpoint 2016 workaround

Since updating to OSX “El Capitan” and Office 2016 I am having trouble recording my lectures. When I switch my Powerpoint presentation to display mode, the beamer screen goes grey (although I can see my presentation on my own laptop). That can be “solved” by disconnecting the displayport cable and plugging it back in again. […]

Pictures save real-estate agents

In the academic discipline of decision-making, experts in general have a mixed reputation. A well-known result is that when comparing predictions of human experts with the predictions of statistical models (based on the same information), models outperform human experts in about 40% of the cases while experts outperform human experts only in about 10% of […]

Showing a pcurve and phack in Stata

As a preparation for the stats course that Daniel Lakens and I will run later this year, I tried to create some Stata do-files related to p-curves and p-hacking. Below my attempts (note: unchecked, comments welcome): pcurves.do Illustrates that p-values closer to 0.05 are more likely when H0 is not true and rejected. phack.do Illustrates […]

TedX Maastricht BrainTrain

I participated in the TedX-Maastricht BrainTrain event: a talk on OddSpot in the Amsterdam-Maastricht train “in a Ted-talk kind of way”. Well … Sort of a surreal experience, including a line-up of speakers ranging from serious to sort of strange, and as usual I managed to look totally weird on the pictures taken (I hope). […]

Social orientation measurement using 1 question

The Social Orientation Value (SVO) is a measurement of someone’s “social preferences”. Literally, it is meant to measure the extent to which you care about what others get. Often, It is measured through the “RING measure” (a tedious procedure with many questions), or through a series of decomposed games. In this latter method, you typically […]

It is about the “process-performance paradox”, and based on a combination of our dearest MAT-2003 database in combination with conjoint analysis.
