You post a Slack in the public channel: "This design has three problems: A has a concurrency bug, B's naming is unclear, C has no tests. Fix and re-review." The Dutch engineer finds it clear and efficient; the Tokyo engineer, reading it in public, feels he's lost face — and quietly closes off to you for weeks.
For low-context (NL/DE/IL): say it all, say it plainly, in public is fine, hard on the issue not the person — they trust directness, and hedging just makes them miss the point.
For high-context (JP/IN/most of East Asia): DM or 1:1, affirm first then circle in, leave a face-saving path. Script: "The overall direction is good. There are two spots I'd like us to look at together to make it more robust — for instance A here under high concurrency… what do you think?"
Default strategy: when unsure, start more indirect + private, then dial up directness by their reaction. Being too indirect with a low-context person is at worst "wordy"; being too direct with a high-context person truly damages the relationship.
"Any concerns? … No? Great, moving on." A high-power-distance team will almost never openly oppose a senior manager at that moment. Weeks later the plan blows up, and only then does someone say privately, "I had a bad feeling about it at the time."
Change the channel: write the plan as a doc and ask everyone to leave comments within 24 hours — written + non-real-time sharply lowers the pressure of challenging a superior in public.
Ask privately first: in a 1:1, "Where do you think this plan is most likely to break?" In private, high-power-distance people will tell you the truth.
Authorize the contrarian: "Priya, I'd like you specifically to poke holes from the 'why this won't work' angle — this is something I'm asking you to do." With explicit authorization, objecting no longer counts as overstepping.
Boss speaks last: the moment you (the most senior) speak, you set the tone — so hold back and leave the room to the others first.
"We already decided this last week. Why are we still debating? Just execute." To consensual-culture people, you skipped due process — their "debate" is precisely the required step for making a decision.
"I'll make this decision top-down because time is tight; but before I call it, everyone please raise objections in this doc within 24 hours. Once locked, we disagree and commit and don't re-open."
For consensual members, front-load an input window; for top-down members, make explicit "who is the decider, and when it locks" (echoing Day 15, Decision Architecture).
"He's Japanese, so he must be indirect" — your layers of circling leave Kenji baffled, feeling you "won't say things straight, don't trust him." You used the cultural average and misjudged the individual in front of you.
Use the dimension as a prior, then observe how this specific person actually communicates and update fast. Self-calibration line: "I'd assumed you'd prefer me to soften things, but you seem to like it direct — so I'll say it straight from now on, and you push back at me straight too."
