Should statements and moral perfectionism
"I should be doing better by now" — the internal rule that makes every shortfall a moral failure.
Key takeaways
- What it is: "I should be doing better by now" — the internal rule that makes every shortfall a moral failure.
- Why it works: Should statements convert a preference or aspiration into a moral obligation, then treat deviation from that obligation as self-evidence of failure or worthlessness. The cognitive mechanism is rule-based appraisal: instead of evaluating the situation empirically ("what happened, and what’s a useful response?"), the "should" evaluates it morally ("what does this say about my worth?"). Albert Ellis called this "musturbation" — the tyranny of musts. The affect result is guilt, shame, or resentment, depending on whether the should is directed at self or others.
- Evidence: Established clinical or therapeutic practice.
- Avoid: Replacing "I should" with "I shouldn’t feel this way" — which is itself a should statement and adds a layer of shame about the shame.
Why it works
Should statements convert a preference or aspiration into a moral obligation, then treat deviation from that obligation as self-evidence of failure or worthlessness. The cognitive mechanism is rule-based appraisal: instead of evaluating the situation empirically ("what happened, and what’s a useful response?"), the "should" evaluates it morally ("what does this say about my worth?"). Albert Ellis called this "musturbation" — the tyranny of musts. The affect result is guilt, shame, or resentment, depending on whether the should is directed at self or others.
How to do it
- 1Notice should/must/ought statements: "I should be further along," "I must always be productive."
- 2Ask: "According to whom?" and "What would actually happen if I didn’t do this?"
- 3Replace with a preference: "I would like to be further along" carries motivation without punishment.
- 4Ask: "Is this actually a moral rule, or is it a preference I’ve hardened into a requirement?"
- 5Examine the standard: is it realistic, context-sensitive, and applied with self-compassion — or is it absolute?
What the evidence says
Clinical practiceShould statements are part of Albert Ellis’s rational emotive behavior therapy (REBT) model, from which Beck’s CBT partly developed. The link between rigid self-rules and emotional distress is clinically well established. REBT and CBT both have strong evidence bases for depression and anxiety.
Honest caveat: Not all "should" statements are distortions — some moral rules are appropriate (I should keep my commitments). The distortion is in the absolutism and the self-condemnation following deviation.
Common mistake
Replacing "I should" with "I shouldn’t feel this way" — which is itself a should statement and adds a layer of shame about the shame.
IX Coach flags should/must language in your reflections and asks you to convert each to a "I prefer" statement — then explores whether the preference is realistic given your actual situation.
