Most product teams treat user feedback as evidence to be weighed. The 11th-century Persian philosopher Al-Biruni had a different instinct: when he traveled to India to study a foreign civilization, he suspended his entire framework of what counted as 'rational' before he started collecting data — not to abandon judgment, but to avoid the trap of measuring a new world with the wrong ruler. Product managers do this backwards constantly. We gather signals from users and filter them through the mental model we already have of the product, which means we tend to find confirmation of what we already believe. Al-Biruni called this the difference between *transmission* and *translation* — transmitting what you observed versus translating it into something your existing concepts can absorb. The insight, brought forward by phenomenologist Edmund Husserl's concept of *epoché* (deliberate suspension of assumption), is that genuinely novel insight requires a moment of conscious framework-stripping before interpretation begins. Practically: the next time you sit down to synthesize a round of research, try writing down the three things you *expect* to find — then set those aside as the very hypotheses you'll examine most critically.

What did you actually expect to find in your last round of user research — and how would you know if those expectations shaped what you heard?
