CORE DEFINITION
The T-chart is a simple decision aid drawn as a T shape. One class of content goes on the left, such as advantages, arguments for, or supporting evidence, and the opposing class goes on the right, such as disadvantages, arguments against, or contradicting evidence. The forced binary comparison converts a diffuse sense about a decision into explicit parallel lists, which reduces confirmation bias because the counter-case must be written down rather than merely assumed away.
SCAFFOLDING EFFECT
Reduce cognitive load
- Use dimension definition: decide what each of the two opposing columns is meant to represent here. - Use both-column rule: fill the opposing side even when you clearly favour one of the options. - Use weight comparison: read the two lists side by side before forming your final judgement.
Anchor fast decisions
The T shape forces a binary comparison, placing one class of content on the left and its opposite on the right. Because the counter-case must be written explicitly rather than assumed away, a vague feeling becomes a visible pair of lists, which lowers confirmation bias and supports a more rational judgement.
