Map the Decision Chain: The Best Pitch to One Person Can Still Be Vetoed by Someone You've Never Met

Mechanism: more people means thinner responsibility, and decisions stall. When one person decides, the responsibility is all theirs and the motive is clear; when a group decides together, no one has to own it alone — "let's wait, let's look at it more" becomes the safest option, so the bigger the committee, the harder it is to decide anything. The trouble with a single thread is that the person who actually controls the budget and the veto has never heard your value, while your carefully crafted persuasion landed on someone with no real voice.

• Industry research · the buyer is a group (large sample, solid direction): Gartner (formerly CEB) research on complex B2B buying repeatedly finds a typical purchase involves 6–10 decision makers (The Challenger Customer, Adamson, Dixon et al., 2015; the ~6.8 average is often cited), and as the group grows, reaching consensus itself becomes the biggest barrier to a deal. Large sample and a stable direction, but it's proprietary institutional research, not a publicly reproducible controlled study — flagged honestly.
• Social psychology · diffusion of responsibility (hard evidence): Darley & Latané (1968, JPSP) showed with bystander experiments that the more onlookers present, the lower the odds any single person steps in to help, because responsibility gets "spread thin" across the crowd. This diffusion of responsibility is a repeatedly replicated classic — and it's the psychological floor under why committees stall and no one pulls the trigger.
• Takeaway · single-threading is a quantifiable risk: dealing with only one contact ties the whole deal to one variable you can't control (they quit / transfer / fall from favor). Multi-threading isn't politeness — it's insurance on the deal.

Boundary: multi-threading doesn't mean bypassing your contact and spraying the org at random. Suddenly going over enthusiastic Sam's head to pester their boss makes Sam feel betrayed — the right move is to climb through them, via their introduction (see principles 3 and 4).

Mechanism: each role's "what's in it for me" differs, so value must be translated per person. The economic buyer answers for total return and risk, the user for their own daily experience, the gatekeeper for "nothing blows up, no blame lands on me." The same feature means something completely different to each. People only act on reasons that mean something to them — hand A's reason to B, and all B hears is noise. You map the chain precisely so you can tell each person their own version of the story.

• Method · four buying influences (field framework, widely used): Miller & Heiman's Strategic Selling (1985) sorts each deal's decision makers into economic, user, technical, and coach — each with different concerns and veto power. It's a field framework the sales world has used for decades, not a controlled experiment, but the direction — segment by role, pitch by role — is solid. Modern methodologies like MEDDIC ("economic buyer / champion") share the same root.
• Psychology backing · self-relevance drives attention and memory: the more information relates to the "self," the more it's attended to and remembered (self-reference effect, Rogers, Kuiper & Kirker, 1977 — a robust finding). This is why only the "means something to me" version gets through — pitch the wrong person and you've delivered a message unrelated to them, which gets filtered out automatically.
• Key distinction · the one who pays ≠ the one who uses: many deals die right here — the user is in love, but the economic buyer who never owns the price kills it with one "too expensive"; or the economic buyer wants it, but frontline users find it a hassle and resist en masse. Cover both ends.

Boundary: the four roles are "roles," not headcount. One person can wear two hats (a small-business owner is both economic buyer and user), and one role can be several people (three department heads jointly vetting). Don't map mechanically to headcount — map by "who answers for which concern."

Mechanism: a decision you can't attend needs a present proxy — and an insider vouching for you is more credible than you vouching for yourself. (1) Purchase decisions happen in internal meetings, hallways, group chats — where you're absent 95% of the time. Without a proxy, your value proposition never enters those rooms. (2) The same sentence, said by a self-interested outside seller, is automatically discounted; said by "one of us," it's taken as a neutral, credible endorsement (social proof + source credibility). A champion speaking for you beats you saying it ten times.

• Method · the champion is a verifiable role (field framework): MEDDIC (originated at PTC / Parametric, 1990s, Jack Napoli et al.) lists "Champion" as one of six elements and stresses the champion must be verifiable — not "likes you," but proven against small asks (willing to introduce, obtain internal documents, arrange meetings). A widely used field method, not a controlled experiment, but the direction is reliable.
• Psychology · source credibility and social proof (fairly hard): persuasion depends heavily on whether the source is credible and "one of us" (Hovland & Weiss, 1951, the classic on source credibility; and Cialdini's social proof principle). An internal champion's endorsement is your claim spoken through a more credible mouth.
• Commitment & consistency · have them do one small thing: once a champion does something small for you (an intro, an internal forward), the "act consistently with my actions" pressure makes them more invested in continuing to help — the small ask is both a test and a deeper bond. (See the influence-principles piece on this site.)

Boundary: don't treat a champion as a tool to squeeze. A healthy champion relationship is win-win — if this lands, they gain a result / solve their own pain inside the company. Keep helping them so "backing you" pays off for them, rather than being a one-way extraction.

Mechanism: a blocker's opposition is loss aversion + status-quo bias + psychological reactance, combined. To them personally, change means a certain loss (more work, shrunken power, carried risk) — losses they feel far more sharply than equal gains — while the status quo is easiest and lowest-blame. And if you rebut head-on and try to "persuade" them out of their position, you trigger reactance: the moment people feel their freedom is being taken, they instinctively grip their original position tighter. So the effective path isn't to beat them — it's to erase the loss they'd carry and hand their autonomy back.

• Psychology · loss aversion + status-quo bias (hard evidence): Kahneman & Tversky's prospect theory — a loss weighs about twice an equal gain (λ≈2.25); Samuelson & Zeckhauser (1988) on status-quo bias. To a blocker, change = a certain personal loss, and opposition is rational self-protection. (Detailed in the "find & amplify the pain" and "the buyer's brain" pieces on this site.)
• Psychology · reactance (hard evidence): Brehm's (1966) reactance theory — when people feel their freedom of choice is threatened, they push back and lean harder toward the threatened option. This is why "persuading a blocker to drop their opposition" head-on usually backfires: the more you push, the more they resist. (Cross-ref psychology, on resisting manipulation.)
• Takeaway · neutralize beats defeat: the goal isn't to out-argue the blocker, it's to make "change" no longer a net loss for them — take on the work they fear, protect their face and turf, leave the decision with them. Remove the loss and the fuel for opposition is gone.

The line: mapping the chain and neutralizing a blocker are both about getting the right value to the right ears — not about going around the blocker to tell tales behind their back, or manipulating internal politics to squeeze them out. Backstabbing may bypass one person short-term, but long-term it destroys the whole org's trust in you, and once discovered, even your champion walks. The clean way: openly get the blocker's legitimate concerns heard and resolved.
