Dan Pink asks Adam Grant: "Okay, let me just get this out of the way. People named Dennis are almost twice as likely to become dentists as people with comparably popular names. What the heck is going on here and why should we care?"  Adam responds: "The evidence here is very controversial, but it does turn out that we’re surprisingly drawn to careers—and people, places, and products—that remind us of our own names. If your name is Dennis or Denise, when you first learn about dentists, you might have a slightly more positive feeling because it taps into something familiar that’s part of your identity. Research by Brett Pelham and his colleagues suggests that this is true for a wide range of names, especially if our names are rare and we identify strongly with them. The self-similarity effect extends to helping: we’re more likely to give time and money to people who remind us of ourselves.  We should care about this for two reasons. First, subtle factors can shape where we direct our giving, and we need to be cautious about helping for the wrong reasons. Second, if we want to convince other people to be more generous, we can often boost giving by showing them how they share uncommon commonalities with others in need."
