What does it mean that default communication style?

How you communicate when not thinking carefully about it is your communication default.

Example: A product manager sends dozens of Slack messages daily without thinking about tone. When she audits a week of her messages, a pattern emerges: every request she makes is framed as an apology. "Sorry to bother you, but could you maybe look at this when you get a chance?" "I hate to ask, but would it be possible to revisit the timeline?" She never noticed the pattern because it runs automatically — inherited from a household where asking for anything directly was treated as imposition. Her team interprets the hedging not as politeness but as uncertainty, and they deprioritize her requests accordingly. Her communication default is undermining her authority thirty times a day, and she has been completely unaware of it for years.

Try this: Collect your last twenty outgoing messages — emails, Slack messages, texts, or any combination. Read them as if a stranger wrote them. For each message, note: (1) the dominant tone (directive, apologetic, passive, aggressive, warm, cold, formal, casual), (2) the ratio of statements to questions, (3) whether you stated what you needed or hinted at it, and (4) any repeated phrases or hedges ("just," "sorry," "I think maybe"). Write a one-paragraph summary of your communication default as revealed by these twenty messages. Then write one specific rule you will apply to your next ten outgoing messages — not a vague intention like "be more direct" but a concrete instruction like "remove every instance of 'just' and 'sorry' before sending."
