Love what the team at Dopamine is building. They've turned their PhD thesis in neuroscience and informatics into a simple API to help developers better understand how to engage and grow users.

@mazzeo Thanks Maz! We ๐Ÿ’• you too
Cracking hunt here @mazzeo love what they are doing here for des helping to user base!
Awesome API! It totally makes sense that variable reinforcement strategies can and will be optimized! Very very excited to check it out and see a ton of value in the service, in a lot of use cases (Education could be really cool)
@bshins Education is a Dope application; we've seen it work. But I think an email app might be even Doper. *wink*
Looks awesome. It would be very cool to see a demo
@ben_stein We just finished the demo video. Hot off the presses:

@tdaltonc @ramsay_brown Love this! Can you talk about differences in retention you've seen by getting timing right vs random timing vs no rewards at all?
@ianmikutel @ramsay_brown Sure! We've run randomized control groups for all of our customers. Compared to a no-reward control, the optimized group has up to 60% higher retention. We don't run random-timing controls very often any more. They are not a good control for the way the newer versions of our algorithm runs. But back when we did, the optimized group has 25% higher retention than a dose-matched-random-timing group. And we're continually finding new ways to do even better. Thanks for asking!
@tdaltonc Thanks! And can you share any data on testing of various rewards? For example, text vs emojis vs stickers vs other stuff?
@ianmikutel The short answer is: not much difference. Skinner pointed out that, "The way positive reinforcement is carried out is more important than the amount." And by-and-large that's what we've found. Above some minimum level, all rewards work equally well. We have found that some rewards work better among different user groups, but nothing systematic. And we've also never worked with a developer that was interested in running radically different rewards, so we've never gotten to test emojis vs stickers (for example) in a single app. We have found that when a developer provides multiple different rewards for a single action, you can do interesting things in the patterns between them (but we're keeping the details on that close to our chest.)
@steveraffner you might be my new favorite person.
@steveraffner @ramsay_brown Next time you're in LA. Please stop by for a free beer.
