I don't think information addiction has anything to do with a particular Meyers-Brigg personality type. They seem like an orthogonal axes. If anything, I would imagine INTP are less likely to have this issue, because they are interesting in meaning and not just information. I would think the more social personality types would be more addicted to news or e-mail, but that's just speculation.

One thing I do is take notes on most things I read. Just a couple sentences. This helps in several ways:

1) If you're not willing to take notes on something, it's not worth reading. So you read less.

2) It limits your rate of consumption, because writing takes time. So you read slower.

3) Having it written down and organized reduces the burden on your brain. It's like the GTD system. You want to relieve your brain of holding information. Your brain will know it is one click away if you have organized your notes properly.

4) When writing notes, you are relating it to things you already know. It forces recall. This prevents your brain from being just a jumble of useless disconnected facts.
