As I’ve said elsewhere, I’m skeptical that the approach to take is to do more such RCTs. I worry about us having to spend extremely large sums of money for such things.
It’s probably a good idea to consider the global amount of money being spent on an AR intervention when evaluating the cost to investigate it. Like how much money is being spent across the different AR orgs on FB ads? If a proper study costs $200K and there is only $500K a year being spent globally, then it’s hard to see the value proposition. If the total being spent annually is $20M, then a full fledged RCT is probably in order.
Does anyone know of estimates of how much the AR movement as a whole is investing in different interventions? This might help prioritize which interventions to study first and how much to pay for those studies.
Vegan Outreach ran its first annual Leafletting Effectiveness Survey (LES) last fall and we had a dismal response rate as well (around 2%). We were offering $5 incentives for people to take a 2-part survey, where Part 1 was filled out immediately and then an email was sent out two months later to complete Part 2 and claim their gift card. We’ve been running small response rate studies since then to figure out what kind of incentives we need to hit our targets, but we’re seeing significant variation based on what city / state we’re operating in. This is making it really difficult to find one incentive level to rule them all.
I wonder if you’ve looked at the geographical distribution of where your 2% came from? And do you have any theories why your actual response rate differed from your pilot response rate?
