Our causal inference summer school, Utrecht 6 - 10 July (€875 for academics) is open for registration!
Last year we added a new day focused entirely on designing a causal research project from scratch in groups - looking forward to doing this again this year!

So much stupid stuff happens when your institutions are motivated by the haunting fear that someone, somewhere is getting something they don't deserve.
This report in Nature on the costs of competing for & administering scientific grants is shocking: "In other words, European taxpayers will have spent more on the funding process than on the funding itself, and the scientific ecosystem has been drained." www.nature.com/articles/d41... 🧪
Point of no returns: researchers are crossing a threshold in the fight for funding
With so little money to go round, the costs of competing for grants can exceed what the grants are worth. When that happens, nobody wins.

It has become received wisdom in Brussels and Washington that there is a new “euro-sclerosis”: that the EU economy is lagging the US
