Exercise 3: Cutting a Necessary Step vs. Reducing Extraneous Load — Possible Solution ==================================================================== Cognitive Load Theory splits mental effort into three real, distinct types - intrinsic (the task's own inherent difficulty), extraneous (unnecessary burden created by how something is presented), and germane (effort spent actually building real understanding). A genuinely necessary step in a tax-filing flow is part of the task's own real complexity - removing it doesn't reduce extraneous load at all, since extraneous load is specifically about presentation, not about the task's own inherent requirements. Removing a step the task genuinely needs instead cuts into intrinsic load - and unlike extraneous load, intrinsic load isn't something a designer is actually supposed to reduce by simplifying the interface, since it reflects the real complexity of the task itself, not how well or poorly that complexity is presented. If the step is legally or practically required, removing it doesn't make filing taxes easier in a real sense - it likely produces an incorrect or incomplete filing, which is a much worse outcome than a genuinely well-presented, but still full, multi-step flow. The correct move to reduce cognitive load here would instead target extraneous load directly - clearer labels, better-organized steps, progress indicators, or removing any presentation-level clutter around the necessary step - none of which requires removing the step itself. ANSWER: This does not reduce extraneous load - it cuts into intrinsic load, the task's own inherent difficulty, which a designer isn't supposed to reduce by simplifying the interface, since doing so risks producing an incorrect result rather than a genuinely easier one. The real way to reduce cognitive load here is to reduce extraneous load around the necessary step (clearer labels, better organization) without removing the step itself. WHY THIS WORKS AS AN ANSWER ------------------------------ This correctly distinguishes intrinsic load (the task's own real complexity, not reducible via interface changes) from extraneous load (the actual target of good UI design), rather than treating "reduces cognitive load" as a single, undifferentiated justification for any simplification.
