S — Same-shaped

You may think you have many options, but if they all work through the same underlying mechanism, you really only have one.

You want to sleep better, so you list your options: a strict 10pm bedtime, a phone curfew, no caffeine after noon, a wind-down routine. Four options, you tell yourself. But three weeks in, nothing has stuck, and you keep cycling through the same list wondering why more choices are not producing more progress.

Same-shaped is a diagnosis: many apparent options that all run on one causal mechanism, which here is you exerting willpower at night when you are most depleted. The cue is that swapping between your options never changes results. To check, run the clone test on any pair: would they start with the same first actions, seek the same evidence, and fail for the same reason? If yes, count them as one option. Then generate something with a different mechanism entirely, like having your partner hold the phone, an automatic router shutoff, or a morning workout that changes sleep pressure. What visibly changes is your list shrinks to its true size, often from six to one, and the gap you need to fill becomes obvious. Skip this diagnosis when your options already differ in actor, mechanism, or timing; then your set is genuinely varied and the bottleneck is choosing, not generating.
