Customer Discovery Mistakes Even Good Interviews Won't Surface

Interview theater feels productive

You schedule calls — polite curiosity rewards you — notes pile — dopamine says learning.

Some traps survive “good” interview discipline — because humans optimize comfort together.

---

Mistake 1 — Hypothesis laundering via leading empathy

You pitch softly — they nod — you log validation.

Sympathy isn’t contract.

Fix: open with neutral scenario prompts — let them name pain before solution leakage.

---

Mistake 2 — Power gradient silence

Junior users speak; budget owners ghost until procurement.

Interview-only truth skews toward individual pain missing purchase reality.

Fix: map economic buyer timeline early — refuse story completion without chain awareness.

---

Mistake 3 — Future tense lying (non-malicious)

People predict future behavior optimistically — especially toward likable founders.

Fix: anchor on past behavior — last time they paid, switched, fought internal IT.

---

Mistake 4 — Selection bias panels

Friendly early users differ from hostile mid-market reality.

Fix: sample skeptics intentionally — critics save margins.

---

Mistake 5 — Insight without commitment ladder

No incremental asks → fake traction.

Fix: small commitments — time, data share, pilot dollars — graded evidence.

---

What simulated opposition adds

Personas emulate divergent incentives — finance vs security posture vs user cynicism — revealing cracks no single human interview mirrors concurrently.

Not replacing empathy — stressing synthesis.

Pair interviews + board-style rehearsal on shared hypothesis briefs — mismatch surfaces faster.
