Have they come up with a way to incentivize following through with plans, or reducing the fear of spending time with somebody you haven't had some contact with?

Have they come up with a way to incentivize following through with plans, or reducing the fear of spending time with somebody you haven't had some contact with? There seems to be a very low social/emotional cost to abandoning plans you make with a stranger that you have not vetted. I can imagine a very high abandonment effect, as you experienced.
