One method I found works disturbingly well is to have a busy life or cultivate the appearance of a busy life. It's counter-intuitive for some and obvious for others, but people will value you more if you are less available whereas they will treat your time with increasing contempt if you can be reached and interrupted easily.
With this reputation in place, people are much less likely to try to trick you into doing what they want, and more likely to try to get you to do things with them.
You have to be a little careful though. If you don't have much social capital to begin with, it could backfire into being ignored altogether. If you overdo it, it may also be counterproductive.
