Depends on the tire. For instance, many of the dedicated track tires grip better with lower pressures. (It used to be "most"; I'm not sure about now.) Most of the actual street tires grip better with higher pressures.
There are exceptions in each, of course, which is why testing is important.
Like redpoint5, I don't like to slow down for corners. So far, I have worn out two sets of tires at "high" pressures, and neither set had significantly more wear in the center of the tread than at the edges.
