Yeah.

Okay.

So the motives and interests of the funders is one issue.

Yeah.

Are there other challenges to reaching a full scale?

Yeah.

So you're saying a potential trap or a potential problem would be if someone tries to replicate these RCTs and finds that in this second case, the SMS messages or the ambassadors don't work or the effect size is a lot smaller.

And then what would you say to your funders?

Maybe you want to be able to point to work that you've done assessing your own impact in exactly your context because you are measuring it and be able to say, well, we do have a good sense of what impact we're having at least.

I guess a long crazy view might be this has been tested quite a lot already.

There's been a big study done by the very best people who do this kind of work, and they found that it worked.

The effect was pretty big.

It also is very intuitive that would have this effect of getting more parents to vaccinate their kids.

Yeah, it's not a wacky intervention that you would have guessed wouldn't work.

And so maybe it's a waste of your attention or a waste of money to be going and doing all that much monitoring and evaluation.

Maybe you should kick that can down the road and wait for another couple of years before going into that.

Interesting.

Okay, so the idea is you'll do the monitoring evaluation later on once you're like trying to grow more.

Yeah, I guess there's a slightly cheap way for you to potentially measure impact, which is a little bit harder at the testing phase when you're only reaching a small number of people.

Because if you're actually growing a lot and you say there's like a thousand villages on your list that you eventually want to reach, but you can't reach them all right away, then you can do a before and after comparison.
