Neuro Framework Three

Friction–Bias Grid.

Every stalled decision is a cognitive cost the brain refuses to pay.

Decisions run on fast, intuitive System 1 and slow, effortful System 2. Customers avoid spending System 2 effort unless the payoff is obvious. The Grid classifies what is blocking a decision into three friction types — cognitive, emotional, behavioral — and prescribes the specific behavioral lever that dissolves each. Not "make it simpler." The matched lever for the matched cost.

Friction

What it feels like

Neuro lever that dissolves it

Cognitive

Confusion, too many options, unclear next step. System 2 cost is too high, so the customer defers.

Reduce choices (Hick's Law), smart defaults, anchoring, progressive disclosure.

Emotional

Fear of loss, distrust, fear of looking foolish. Loss looms ~2× larger than the equivalent gain.

Re-frame loss → gain, social proof, authority, guarantees, reversibility.

Behavioral

Too many steps, high setup cost, inertia. The status quo wins by default.

Cut steps, prefill, reduce first-action cost, commitment devices.

The science — Dual-process theory (Kahneman) explains the reluctance to spend effort; prospect theory and loss aversion (Kahneman & Tversky) explain emotional friction; choice overload (Iyengar & Lepper's jam study) explains cognitive friction; and Cialdini's principles — social proof, authority, commitment — supply the counter-levers.

Outcome · 01

Diagnosed

the dominant friction at each decision moment is named, not guessed.

Outcome · 02

Matched lever

the specific behavioral mechanism is applied to the specific cost — no generic "simplify."

Outcome · 03

Conversion

drop-off, abandonment, and stalled upgrades fall as the blocking cost is removed.
