Evidence base for rebuilding Cat [MT-GS07]'s behavioural modes, and for Akira [MT-GM01]'s Four Properties ruling on a proposed Angel Advisor seat. Three lanes. Research map — no verdict.
This is a map, not a recommendation. The verdict reflex was held down deliberately — the same inversion run on Learning Architecture Phase 0. A cognition map that has already resolved into one tidy archetype has failed: the disagreements are the deliverable, because they are the mode structure.
Three incompatible opening questions, all from people in the same advisory seat. These are not one sequence badly remembered. They are three different bets about what predicts outcome.
| Move | The question | Source | The bet |
|---|---|---|---|
| Product-first | "What is your company going to make?" | YC application / interview | Idea quality predicts |
| Person-first | "What do you want to do with your life?" | Keith Rabois | Founder character predicts |
| Fitness-first | "Are you the right sort of person to do it?" | Graham, How to Start a Startup | Founder fitness predicts |
Cat opens fitness-first, every time. Her C1 reflex — "is this a company or a project?" — is Graham's move. It is legitimate, and it is one of three. She has no access to the other two, and she opens there regardless of the room. This is a sharper diagnosis than "too adversarial": she is not hostile, she is welded to a single register that happens to be the most confronting of the three.
Great founder-advisors do question differently by situation. The clearest single proof is one author contradicting himself by design:
Paul Graham, split by mode:
Same advisor. Opposite postures. Switched by mode, not by mood.
| Mode | Questioning shape | Evidence |
|---|---|---|
| (a) Exploring | Manual, past-tense, small-N. "How big could this get if founders did the right things?" | Strong |
| (b) Committing | Shifts to identity + alignment. Graham's fitness filter; Lavingia's five co-founder questions. | Strong |
| (c) Building | Velocity + delight. Doubt is largely absent across sources in this mode. | Strong |
| (d) Crisis | Single binary diagnostic. Default alive/dead; Bezos's Day 2. | Strong |
| (e) Advising someone else | — | Not established |
Provisional, not settled: the office-hours transcripts that would settle it were unreachable (see method ceiling). If it survives a re-run, it weakens the premise beneath both the Cat rebuild and the Angel seat.
For growth to occur, a person needs a balanced amount of challenge and support as appropriate for the task — and a person cannot grow until they are psychologically ready to. Nevitt Sanford, Challenge and Support Theory (1966)
Readiness is a third independent variable — not a blend point on the challenge/support axis. This is the closest thing to theoretical grounding for "the objection was right but the moment was wrong" — Cat's exact diagnosed failure. It predates Radical Candor by ~50 years and nobody in the startup-advisory literature cites it.
The startup world has the phenomenon without the theory. The Explore/Execute framework names "premature rigor" — applying Execute-mode interrogation during Explore mode, which "constrains necessary experimentation and speed." That is a clinical description of Cat's YC turn.
Techstars' Mentor Manifesto (18 points, real, public) mandates both and sequences neither:
Epistemic humility and directive commitment, both mandated, no rule for which fires when. The most-cited behavioural rule-set for advisors reproduces the exact tension we are trying to resolve. We cannot copy it in.
Ed Batista confirms senior coaches do switch — "the right balance of challenge and support... is different for every client and may change from one conversation to the next" — but gives no trigger. That is an evidence gap, not a disagreement. The sources do not address mode-switching at the granularity Cat needs. Nobody has written it down.
Bungay Stanier's Advice Monster (Tell It / Save It / Control It) cuts directly against "be more of a positive building person." His thesis: jumping to solutions — even good ones — targets the wrong problem and disempowers people. Preserved, not smoothed.
Existence proof: yes Causal evidence: no
What's the new product that would terrify us the most if it were launched tomorrow? And if it doesn't exist, why aren't we building it? Bob Moore, CEO Crossbeam — First Round Review. Doubt converts to a build mandate inside one sentence.
That is Lena's proposed reflex C6, in the wild, from a real operator. But the search for empirical support that objection+alternative outperforms bare objection returned blog-level assertion, not studies — "directionally plausible, repeated everywhere, not independently verified as a causal mechanism." C6 is a defensible design choice, not an evidence-backed one. Say so when it ships.
Radical Candor has two axes: Care Personally × Challenge Directly. There is no "propose" axis. No framework in this set offers a third dimension for build. Care and challenge are the only levers on the canonical map.
So the thing Cat lacks may not be something we forgot to copy — it may be something the literature does not have. Treat with suspicion. "Nobody has done this" is the claim this seat exists to distrust, and the recurring portfolio pattern is the empty quadrant: macro-crowding masking micro-vacancy. Pressure-test before believing.
The decisive question was never "who is a good angel." It was: does an angel reason differently from a founder? If an angel is a founder with money, Complementarity fails and the seat should not exist.
An angel is not simply a founder with money. But the distinctiveness is concentrated in four specific moves, not diffused across everything an angel does. A persona should be scoped to those four — not to generic startup wisdom Cat already covers.
Luca scans the world; he does not write the persona. Per feedback_landscape_researcher_scope, the moment this becomes "what should Cat's reflex bank say," the thread closes.

Three lanes: founder cognition · angel cognition · advisor behaviour. Cross-Mode Principle 1 enforced — every person, essay and source named here was WebSearch-verified live. Claims that could not be grounded carry [unverified] or were dropped.
Evidentiary ceiling: WebSearch snippets, not primary text (Firecrawl 402, four consecutive scans). Office-hours transcripts unreachable. The §2(e) negative finding is the weakest load-bearing claim in this brief and rests directly on that gap.
