Choice overload describes the difficulty of comparing an unwieldy set of options. Fewer choices are not always better; the clarity of their differences also matters.
The demo switches between four and twelve cards to show the growth in comparison work. It does not invent a measured decision time or abandonment rate.
Instead of hiding options indiscriminately, group by use case and offer useful filters and comparisons. Validate the structure against real customer tasks.
When to use
Use it to structure the first decision in a catalog or plan selector.
