Some things to say:
First: I have to admit I thought Harris might win. I was cautious in my public statements but internally thought she might win. I was wrong and I am happy that with my statements I stayed cautious.
Second: About the wrongness of the polls. Actually the reason why they were wrong was called out before the election already, by statistician Nate Silver. He saw herding. Which means different polls are closer together than statistically should be happening. Which means pollsters that have results that are outliers fear about their reputation and change some parameters to be more in line with other polls. This happens with all polls and they end up pretty close. The point they are herding around hasn't to be the middle of the polls, it can lie on either side. In this case one might suspect if the pollsters more trusted their own polls we would have seen some polls more pointing in Trumps direction. So we should learn: if all the polls are telling the same story it doesn't mean they are right - on the contrary.
