Study of 2.5 million children finds no link between MMR vaccine and autism
Evaluating the health records of over 2.5 million children, researchers found no evidence that receiving the measles, mumps, and rubella vaccine before age two increases the risk of a childhood autism diagnosis.

Surprisingly, snapshots from everyday life of that time likewise amplified happiness, but were less effective antidotes to negative emotions. Overall, showing pictures about Nazi terror in combination with other pictures from that time seems to reduce the impact of the terror pictures.

Kai Sassenberg @kaisassenberg.bsky.social · 31/03/2026
A fifth study (N=642) conducted online does not replicate this effect. An integrative analysis of considered emotions, however, implies that glorifying propaganda images may be doubly vicious: they reduce negative and enhance positive emotions experienced after reminders of atrocities.

Kai Sassenberg @kaisassenberg.bsky.social · 31/03/2026
We investigate how the propaganda images glorifying Adolf Hitler influence these feelings. In four laboratory studies (total N = 429) Germans expressed weaker guilt when pictorial reminders of the atrocities committed during the Nazis' redesign were mixed with glorifying propaganda images.

Motivated by the redesign of the exhibition at the Obersalzberg Memorial we studied the effect of these pictures among nowadays Germans. The atrocities committed during the Nazi era still affect Germany's image in the world and Germans' feelings about their country's past.

During the Nazi period cigarette boxes contained codes that could be traded for collectable pictures that showed Nazi propaganda. More than 4 billion of these pictures have been sent out. Some of these pictures were glorifying the Nazi regime.

Kai Sassenberg @kaisassenberg.bsky.social · 31/03/2026
We focused on the impact of glorifying propaganda and found that showing these pictures (but also showing neutral pictures from the Nazi period) among pictures about Nazi terror reduces negative and increases positive emotions.

We firmly believe that, in such cases, anonymized data are the better option and non-anonymized data should, if at all, be published in a repository allowing restricted access for scientists.
110
Kai Sassenberg @kaisassenberg.bsky.social · 19/03/2026
We conclude that the sample (e.g., the analyzed original publications) and the data per publication, with an anonymized ID, should always be published. However, we argue that publishing non-anonymized data might cause unjustified harm to original authors (e.g., errors in human coding).
