People jump to all kinds of conclusions about you when they read documents you have written. They decide, for instance, how smart, how creative, how well organized, how trustworthy, and how considerate you are. And once they have made up their minds, it is hard to get them to see you differently. Research in social psychology shows how sticky early impressions are. It takes serious work on the receiving end to undo them — work that your colleagues, customers, and partners may not have time (or feel motivated) to do.
