Our brains retain unfinished tasks better than completed ones due to a cognitive tension that keeps this information active.

The Zeigarnik effect is a well-documented concept in cognitive psychology, initially demonstrated by Bluma Zeigarnik in the 1920s (classic observational studies). Research confirms that interrupted or unfinished tasks do indeed create a form of psychological tension that facilitates their recall, as highlighted by a meta-analysis published in 'Perspectives on Psychological Science'. What the creator presents is consistent with the scientific consensus, although the persistence of this tension varies depending on the individual and the complexity of the tasks. It is accurate to state that this mechanism is leveraged in marketing (suspense, cliffhangers) to maintain engagement. There is no major exaggeration here, as the creator acknowledges the ambivalent nature of this effect: it can assist with motivation while also becoming a source of mental overload if managed poorly.
