Duck Tales: How we use mental models and operational defaults to improve decision making (Ep.39)

In this episode, Beah (Chief Product Officer) and Marc (VP, Engineering) discuss how we create, communicate, and challenge operational defaults to make better decisions at speed.

In each episode, you’ll hear from employees about our vision, product updates, engineering, or approach to AI. Today, you are going to hear about how we work, I guess, or one facet of how we work, which is using operational defaults and I have with me Marc, who is going to who I’m going to interview about operational defaults. Marc, do you wanna introduce yourself?Marc: Yeah. Marc, I’m on the engineering team at DuckDuckGo.Beah: Okay. That’s about all you need to know. and I’m Beah, I’m on the product team if if you haven’t seen me before. okay, cool. Well let’s jump in. What even is an operational default?Marc: Yeah. Yeah, so defaults are I would say a deceptively simple concept. at at DuckDuckGo we’re always trying to leverage mental models to help us move more quickly and think more clearly and and things of that nature. in that context, the default effect is seen as a negative, right? And and I think we’ve all seen that in apps and in different places. Here we’re trying to leverage the the upside of that, where we’re basically taking any decision that you can make ahead of time that generally is true or has a right answer eighty percent of the time, we’re gonna call that a default. for that other twenty percent, we wanna leave room for our folks to be able to make exceptions, ideally very thoughtful exceptions.Beah: When you say default is a negative in the app, you mean like, you know, if you get an Android phone and the default browser is Chrome and the default search engine is Google and it’s really hard for another player like DuckDuckGo to to break through th those defaults. Is that right? Yeah. Okay.Marc: yeah, exactly. There’s there’s in Gabe’s book of mental models there’s the default effect and again it’s generally negative, but like I said, in this case we’re trying to use defaults as as something that we can leverage to help us go quicker.Beah: Yeah, yeah. So how is that how is it different than a rule?Marc: I mean it’s conceptually the same thing. I think rules are just more binary, right? Like this is something you do or you don’t do pretty much all the time. Where here we’re saying that these are things that are generally true. Like I said, eighty percent of the time is just the number that we made up. and that allows people to potentially make faster decisions. but we also want to include encourage people to think about what they’re doing and not just go on autopilot. And I think that’s the danger of catching something as a rule is that yeah, people will just kind of blindly follow it by default.Beah: Yeah, yeah. I think that distinction is super important. Like, first of all, there are a lot of things where rules just have exceptions and therefore they’re not really good rules, you know? like you have to be pretty sure that there has to be a really good reason to make something a rule because it’s going to fit different situations differently. And yeah, it’s like once it becomes a rule, people like lose power to do anything differently, so they don’t think about it, they don’t feel empowered, and like with a default, there’s still a burden of judgment because you can overturn the default and choose a different path. but the idea, I think, would you care would you say this is a fair characterization is like A, don’t spend brain power thinking about like reinventing the wheel or thinking about something that doesn’t really warrant brain power, like there’s a good default, and B you know just to n to nudge people in the direction of the best average answer, you know.Marc: Yeah, right. It’s lev
