When we see a disaster strike, it’s a knee-jerk reaction to want to help. It’s possible, however, that despite your best intentions your charitable act may be more of a hindrance than a help. That flies in the face of everything we know about disaster relief – these people need as much as they can, as quickly as they can get it, right? But often our generosity isn’t informed by humanitarian logistics; good intentions can do harm if they lack understanding, as Albert Camus once wrote.
