The fact is that modesty, or even self-effacement, can be more effective than bragging in creating a good first impression. Most of us know this from being on the receiving end, yet we still err on the side of self-aggrandizement. But why do we get it wrong so much of the time? Here's where some new research may be illuminating.
Studies show that the more you toot your own horn, the more negatively you're evaluated: Self-promoters are not only less liked, but also earn lower salaries and fewer promotions. Bragging about yourself violates norms of modesty and politeness -- and if you were really competent, your work would speak for itself.
