Why do people have "blind spots" about the things they do themselves?

Question

For example, they accuse others of intolerance, but they also have their minds made up about things. They may be suspicious of others' motives, but are up to something themselves. In other words they see the fault all around them but never recognize it in themselves and never ask why they see so much of it.

Answer 1

You mean they fail to remove the beam in their own eye while working on the mote in yours? Well, don't you want that mote out, anyway?

So often people can give advice better than they can take it. I am very good at giving young girls advice on not getting fat in part because I am the example of what not to do: I weigh over 300 pounds.

And of course there is the element that someone who is dishonest or disingenuous will come to expect that in others. Being "up to something" is what they expect everyone is: having a hidden agenda. And in fact, don't we all have items on our agenda that we keep to ourselves? If not from shame, then to avoid stating the obvious, or because you assume everyone else has similar items. Or simply to avoid being boring!
