Anchoring Effect vs Framing Effect

Anchoring pulls judgment toward a starting value; framing changes judgment by changing how the same substance is described.

Anchoring effect

Core pattern

An initial number, estimate, or reference point drags later judgments toward itself.

Ask: What estimate would people make before seeing the first number?

Framing effect

Core pattern

Different descriptions of equivalent substance produce different judgments.

Ask: Would the preference survive a neutral wording or the opposite frame?

Why people mix them up

A first number can also be a frame, especially when it makes later options feel cheap, expensive, risky, or safe.

Quick rule

Ask whether the distortion is caused by a starting point or by a presentation shift.

Diagnostic questions

Use these before deciding which label should carry the lesson.

Can you remove the first number and still reproduce the shift?

Can you restate the same facts in gain and loss language and watch the preference move?

Is the reference point numerical, narrative, emotional, or all three?

Mini cases

The same surface area can point to different underlying mechanisms.

Anchoring effect

A salary negotiation starts high and every counteroffer stays near that number.

Why: The opening number is the active pull.

Framing effect

A policy gains support as '90 lives saved' and loses support as '10 lives lost.'

Why: The same outcome changes force when the description changes.

Repair Move

Change the process, then choose the label.

Make an independent estimate first, then restate the decision in at least two equivalent frames.

Study the entries

Use the comparison as a bridge into the fuller pages.

Anchoring effect

The tendency for the first salient number, frame, or option to pull later estimates toward itself even when it is arbitrary or weakly relevant.

Framing effect

The tendency for the same underlying information to produce different judgments depending on how the options or outcomes are described.
