When should we see it?

Single-process theories

Selective/Pre-emptive conflict resolution

Corrective/Default-Interventionist

Competitive/Parallel-Competitive

Intuitive logic

- Implicit conflict detection
- Slow beliefs, fast logic

An archetypal dual process task?

A bat and a ball cost £1.10 in total.

The bat costs £1.00 more than the ball.

How much does the ball cost?

A bat and a ball cost £1.10 in total.

The bat costs £1.00 more than the ball.

How much does the ball cost?

A bat and a ball together costs £1.05.

A bat costs £1.

How much does a ball cost?

Attraction to heuristic response when selecting correct one

...but not the other way around.

Easy vs. hard logic

Conflict detection

vs.

*Criterion S?*

In forced choice

Uncertainty ≠ Conflict

→ Rationalisation?

Single process?

Can the mice be trusted?

...or do the eyes have it?
