I am in New York attending the Eastern Economic Association meetings. I was in an agent-based modeling session in which two partticipants participated by internet because they were both refused visaas to enter the US. One was from Turkey, which I think is under strict review by the current administration. The other, a woman from India, working for an American think tank in Toronto, may have simply been a victim of somebody messing up and being too slow in getting the appropriate application forms in on time. But I am sure the deal on the Turkish participant was new policy.
Visa Restrictions And Intellectual Degradation
Their presentations, on self-organizing hierarchies and cryptocurrency dynamics, mostly got through to us. But even with this high-tech ABM crowd there were problems and glitches and occasional disconnctions. It should not have been this way.
This is just dumb obvious. You arbitrarily keep smart foreigners out of your country, this will lead to intellectual degradation.
