The current study explores the association between place features (e.g., schools, public transportation nodes, bars and restaurants) and perceived unsafe locations using data from two open-ended items...

A new Chinese law regulating influencer speech has gotten applause from social media users and commentators who want similar policies in their own countries. But the truth is far from what's in the news and it's a sad reflection of our internet and media space.

Why impact evaluations are so important: not everything that sounds like a good policy actually has the desired impact. While many interventions are highly effective, others don't work at all:

Arriving Malmö again after two pretty hectic days. I have done Lysekil-Malmö-Stockholm archipelago-Malmö since yesterday morning (14hrs travel), and in between done a lecture and a seminar at our masters program and two presentations at a conference by the Swedish prison service.

This evening I have looked at criminology journal rankings a bit. I noticed that the google scholar rankings (h5) had somewhat different rankings than clarivate (IF). British journal of criminology for instance is ranked #1 in google, but only #16 in impact factor. This seems to be due to method. 1/

Trump suggests Khashoggi had it coming: "You're mentioning someone that was extremely controversial. A lot of people didn't like that gentleman that you're talking about. Whether you like him or didn't like him, things happen. But he knew nothing about it. You don't have to embarrass our guest."

A new report from the Swedish police authority is highly critical to its own ability to perform analysis for crime prevention. The police intelligence is not providing analysis for local police to base crime prevention on, nor for assessment of effects.

I haven’t read the full piece, but the argument in the quote seems to be of the form “some good were produced without this” (leaving unsaid “and quite a lot of bad results, too”).
But the argument for pre-registration isn’t that it leads to good results, it’s that it makes results more trustworthy.
