A research study by Einar claims that reduced CPU usage in mobile apps directly causes users to uninstall them faster—yet the data shows only a weak correlation and ignores new security features released simultaneously. What fallacy does this represent?

Title: Why Einar’s Research on CPU Usage and App Uninsts Falls Short: A Closer Look at Logical Fallacies in Tech Analysis When evaluating research in mobile app performance and user behavior, distinguishing robust evidence from misleading conclusions is essential. One recent claim by researcher Einar suggests that reduced CPU usage in mobile apps directly causes users to uninstall them faster—yet a critical analysis reveals this conclusion rests on weakened data and overlooked confounding factors, most notably the simultaneous rollout of major security features. More importantly, the statistical relationship cited represents not causation, but a weak correlation erroneously interpreted as a direct cause-and-effect link—a classic example of the post hoc ergo propter hoc fallacy. What Is Post Hoc Ergo Propter Hoc?
This Latin phrase translates to “after this, therefore because of this.” It describes the logical error of assuming that because event B follows event A, A must have caused B—ignoring other potential causes, omitted variables, or coincidental timing. In the context of Einar’s study, declaring reduced CPU usage directly causes faster uninstalls overlooks crucial complexities: user behavior is influenced by a web of factors, including security updates, user interface design, software bloat, and external peer influences. Evidence of Weak Correlation
While Einar observed that apps with optimized CPU performance saw more recent uninstall spikes, the strength of the correlation remains marginal. Weak statistical links fail to isolate CPU usage as the primary driver—especially when uninstalls can also be triggered by security updates that improve user trust or introduce mandatory app removals for compliance. Without controlling for these variables, the claim overstates CPU efficiency as the dominant factor.
