I'm not sure people realize how much poll results will vary through chance alone. https://fivethirtyeight.com/features/biden-has-made-some-modest-gains-after-the-debate/

Now, it's pretty clear that Biden has gained ground, from +7 before to +8 or probably more like +9 once we've thrown today's polls into our average, but with a +8 or a +9 you're going to get your occasional +3s (TIPP) or +16s (CNN) and that's OK.

In fact, it's good! It's good that pollsters are publishing these results instead of sitting on them. And this is one of those times when a large movement in the race is *plausible*. But we have a lot of polling at it mostly suggests more modest gains for Biden.
