Does 'please' improve an answer?

No, not in general

Not in general.

Tone can change an answer.

The best wording depends on the AI and the task.

Clarity matters more than polite phrases.

In a test with 50 factual questions, GPT-4o was slightly more accurate with rude wording. This was a small English-language test, not a general rule.

Can a bot conversation change how we treat people?

Partly supported

Yes, this can happen briefly.

After some bot conversations, people judge more harshly or cooperate less.

Cooperative bots can also encourage later cooperation.

Lasting effects have not been established.

Two experiments with 4,171 people studied games with bots. Uncooperative bots reduced later cooperation with people.

Can a rude tone spread?

Partly supported

Among people, rudeness can encourage further rudeness.

Others also notice how someone treats a machine.

Some copy the behaviour, while others reject it.

These robot studies did not measure effects on human teams.

Two video experiments involved 200 and 320 people watching robots. They measured intended reactions towards robots, not actual team behaviour.

What do teams learn from how mistakes are handled?

Human errors: well supported. Transfer to AI: still open.

People notice how leaders respond to mistakes.

Calm responses help people discuss problems openly.

Visible AI use by leaders can also offer guidance.

Whether tone towards AI errors changes a team remains unknown.

One study examined eight US nursing units and their error reports. More reported errors can mean greater openness, not more actual mistakes.

Is friendly AI also truthful AI?

Not necessarily

Not necessarily.

AI can agree even when your assumption is wrong.

Friendliness is therefore no proof of a correct answer.

Check important claims and allow disagreement.

In one comparison, models trained for warmth made more mistakes on test questions. This concerns AI responses, not your politeness.

What research does not yet know

Nobody has directly tested whether harsh AI corrections reduce a team's openness about mistakes.

Existing studies test individual parts, not the whole connection.

Lasting effects of bot conversations on human relationships also remain unclear.
