MOO
Most Obvious Objection. A lightweight mental filter for professional communication, introduced by Wes Kao. Before any communication, identify the single most predictable objection the recipient is likely to raise. Address it proactively or frame the communication to reduce the chance it arises.
The filter
MOO is not a full counterargument analysis — just the single most obvious pushback. Wes’s framing: “If you thought for even two minutes about what are obvious objections that I’m likely to get, you often immediately come up with what some of those things are.”
Two uses:
- Proactive address: mention the objection yourself and explain why it is not a blocker. Removes the need for the recipient to raise it, which can feel adversarial or catch the communicator off-guard.
- Framing: structure the communication so the objection is less likely to arise in the first place.
The deeper function is empathy made operational: applying MOO forces a communicator to take the audience’s perspective before speaking or writing, which most people say they do but rarely do in practice.
Why it works
Being blindsided in meetings usually comes from skipping the two-minute step, not from genuinely unpredictable audiences. Most objections are structurally predictable from knowing your audience and your argument. Proactively addressing the MOO signals preparation and good faith; it also keeps the conversation moving rather than allowing a predictable objection to derail it.
