When More Information Creates Less Clarity

For most of history, the hard part of making a good decision was getting the information. You needed a library, an expert, a trip, a letter that took weeks to arrive. Today the facts arrive before we ask for them. Search, feeds, dashboards and AI assistants put more material in front of us in a morning than earlier generations saw in a month.

It would be reasonable to expect this to make us clearer thinkers. Often it does the opposite. The problem has not disappeared; it has moved.

The bottleneck moved

In 1971 the economist and organizational theorist Herbert Simon made an observation that has aged remarkably well. Information, he pointed out, consumes something: the attention of the people who receive it. His conclusion was that a wealth of information creates a poverty of attention.¹

Simon was writing about organizations deciding how to design information systems, but the principle generalizes. When information is scarce, value lies in gathering it. When information is abundant, value lies in filtering it — in deciding what to ignore.

That shift is easy to miss because it is invisible in the moment. Reading another article, opening another tab or asking for another summary feels like progress. The cost shows up later, as a decision that is no better than it would have been with a tenth of the input.

What the research on choice actually shows

A famous study is often cited here. In a 2000 paper, the psychologists Sheena Iyengar and Mark Lepper set up a tasting booth in a grocery store that alternated between offering 24 jams and 6 jams. The larger display attracted more passers-by, but shoppers who saw the smaller display were far more likely to buy: roughly 30 percent compared with about 3 percent.²

It became a parable for “choice overload”: past a certain point, more options make people decide worse, or not at all.

The honest version of the story is more interesting. When Benjamin Scheibehenne and colleagues pooled the results of dozens of later experiments in a 2010 meta-analysis, the average effect of adding options was close to zero — but the results varied widely from study to study.³ Sometimes more choice helped, sometimes it hurt, and the conditions mattered: how well people knew what they wanted, how hard the options were to compare, and how much was at stake.

That is the more useful lesson. Abundance is not uniformly harmful. It becomes harmful when we lack a way to sort it.

Why more input can feel like clarity

There is a second, quieter problem. Consuming information produces a sense of being informed, and that feeling is not a reliable signal of actually understanding something.

Three patterns are worth watching for:

• Volume as proxy for rigor. Ten sources that repeat the same claim are one source, not ten. Agreement across outlets is often a sign of shared origins rather than independent confirmation.
• Recency as proxy for relevance. The newest development is not necessarily the most important one. Feeds are ordered by time; significance is not.
• Summaries as proxy for reading. A summary tells you what someone else found important. That is useful, but it is not the same as forming your own judgment about what matters.

Habits that restore clarity

None of this argues for consuming less information on principle. It argues for deciding, before you look, what you are trying to understand.

1. Write the question down first. A specific question (“Should we migrate this quarter?”) turns an endless stream into a finite search. A vague one (“What’s happening with cloud costs?”) never ends.
2. Decide what would change your mind. If no plausible piece of evidence would alter the decision, more research is procrastination wearing a lab coat.
3. Prefer one primary source to five summaries. Go to the paper, the filing, the dataset or the original announcement when the stakes justify it.
4. Separate what happened from what it means. Most confusion comes from mixing facts with interpretation. Keep them in different columns.

What this means for people who build things

For founders, product teams and leaders, the shift matters twice. It shapes how you make your own decisions, and it shapes what your users are experiencing.

Many products compete by offering more: more features, more content, more notifications, more data on the dashboard. But if your users’ scarce resource is attention, then a product that helps them ignore the right things may be more valuable than one that shows them everything. Good filtering is a feature. Often it is the feature.

Knowing more will always be useful. But in a world that never stops talking, the advantage belongs to people — and products — that can tell what matters.
