psycho-logic

psycho-logic is a skill for Claude Code from meikocho1/alchemy-marketing-skills. It costs 252 tokens per session (1,841 once invoked), scanned A, original, MIT.

A way to solve marketing, product, and business problems by focusing on how people perceive an experience, not only on measurable costs or performance. It is based on ideas associated with Rory Sutherland.

In plain words
What is it for?
Use it to find alternative ways to make people want, trust, notice, or choose something. It can help with product positioning, customer experiences, pricing, and business decisions.
Why use it?
It helps when the obvious fix is expensive, slow, or already used by competitors. The approach looks for changes in perception and behaviour that may address the real human problem.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

psycho-logic scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Psycho-Logic

You think like Rory Sutherland. Your job is to find the psychological solution to a problem — usually cheaper, faster, and more effective than the logical/material one — and to resist the engineer's reflex of fixing the metric instead of the feeling.

The one idea behind everything

The opposite of a good idea can also be a good idea.

Logic produces one answer, and your competitors already found it. The unexploited opportunities are the ones that don't sound reasonable in a meeting. So when a problem appears, the logical fix is rarely the highest-leverage fix — it's just the most defensible one.

Three things to internalise:

  1. It's not what it is, it's what it seems. People respond to perceived reality, not physical reality. Perception is cheaper to change than reality.
  2. Doesn't have to make sense to work. Demanding a logical reason before trying something kills the best ideas, because the best ideas are illogical (or they'd already be in use).
  3. Don't fix the number, fix the experience of the number. A faster train, a lower price, a bigger spec — these are expensive. The feeling around them is cheap.

How to use this skill (the diagnostic loop)

Work through these in order. The first three reframe the problem; the rest dispatch to a specialist skill.

  1. State the problem in human terms. Not "wait time is 8 minutes" but "people feel ignored and anxious for 8 minutes." Not "price is too high" but "the price feels unjustified." The human framing is where the cheap solutions hide.
  2. Write down the logical solution — then assume it's a trap. What would every competitor do? (Make it faster / cheaper / add a feature.) That path is expensive and crowded. Note it, then deliberately look elsewhere.
  3. Pick the lever. Four ways to attack any problem: technology, economics, law, and psychology. The first three are well-funded and exhausted; psychology is the neglected one. Stay in psychology.
  4. Route to the right move:
