Absolutely. At work I realized that if I have paragraphs in emails most people will just read the first sentence and ignore the rest. I have resorted to breaking paragraphs in to very easy to follow bulleted lists and that seems to help a little bit.

I think the most common reason for this is that it forces people to go out of their routine/comfort zone to understand something, which many people aren’t willing to do, either consciously or subconsciously.
