I'm wondering: how many people have noticed changes in the quality of their interpersonal reactions after becoming 'more rational' than they were before learning about applied rationality? How would those changes in quality be judged from both outside and inside views?

(I use quotes, as each person will have a different metric by which they will judge an increase in rationality - and I can't think of a standard metric everyone can use for purposes of answering this query. To mitigate this variable, please state the metric you're using.)
