# Ovsiankina effect The Ovsiankina effect is our tendency to go back to a task that was interrupted before we finished it, even when nobody asks us to and there is no reward for doing so. Maria Ovsiankina, a student of Kurt Lewin, reported it in 1928: when participants were given the opportunity after an interruption, they tended to resume the unfinished tasks on their own. It is the sibling of the [[Zeigarnik effect]], which came out of the same lab a year earlier and claims that we *remember* unfinished tasks better than finished ones. Both were explained by Lewin's idea that an intention creates a tension that only goes away when the goal is reached. The two have aged very differently. A 2025 meta-analysis by Ghibellini and Meier found no general memory advantage for unfinished tasks, but a reliable tendency to resume them. The authors note that Ovsiankina studies mostly report resumption rates descriptively and measured them in heterogeneous ways, so the size of the effect is hard to pin down, but its direction is consistent. Why it matters: the honest version of "unfinished tasks stick in your mind" is "unfinished tasks pull you back". That pull is useful when you stop mid-task on purpose (leaving an easy next step makes it easier to restart), and costly when you have many [[Open loops]] competing for your attention. Each one keeps tugging at you, which is one reason to [[Limit Work In Progress]]. ## References - Ghibellini, R., & Meier, B. (2025).
