Have you ever reacted to something you noticed by saying "Bizarre!" or "Weird!" or "How strange"? Example: "Hey, Michael's post is tiny this week. Weird!"
Have you ever investigated to learn why what you noticed occurred? Or did you make an assumption about its provenance? Or did you drop it and move on?
The next time you notice yourself reacting in this way, reframe your response and say "How interesting that <what you observed>. I wonder why <that happens>." "How interesting that Michael posted a minute blog entry this week. I wonder why he didn't write something longer."
Now think of five explanations for what you noticed. Then think of five more. And five more. And five more. When you can't think of any more, come up with five more. He didn't have anything interesting to say this week. He self-censored everything he *really* wanted to say. He was pressed for time and didn't have time to write more. He didn't really have time to write anything this week yet didn't want to disappoint his loyal readers. He paid someone to write his blog entry this week and they didn't do a very good job. Michael usually ghostwrites for someone else, and that person is on vacation, and so he had to do it all himself this week. . . .
Once you have really and truly hit the bottom of your imagination barrel (hint: the first three times you think you've hit it, you haven't yet), review your list and pick the explanation you believe is most likely to be correct. Then talk with the person whose action engendered all this activity and Check It Out!
