It seems like there are largely two drivers:
- They believe very strongly in the cause
- This means that credibility flows from the cause to the person.
- In this scenario raising money is all about emphasizing how your work is the best solution to the problem.
- They believe very strongly in the person
- This means that credibility flows from the person - they essentially would support more or less any cause that this person is leading.
- In this scenario personal relationships (or perceived personal relationships) matter the most.
It's because they know (or feel as if they know) the charismatic leader that they open their wallet. If a friend approaches me - as long as I don't disagree with the cause - what dictates the amount of money I'm willing to give is not how strongly I believe in it, but how close a friend they are. I simply don't have time to understand the complexities of that particular issue and compare various solutions. Instead, the best I can do is rely on the person presenting the case. The more I trust them (and their own research) the more confident I am in their solution.
Granted that this doesn't mean that in fund-raising you shouldn't explain any actual evidence and just beg your friends for $$, but focusing on relationships does change the entire way you frame, brand and market your cause. It's for this reason that social media (has) and I think, will continue to have a major impact on charity fund-raising.
