Two scientists at Microsoft Research, Jake Hofman and Dan Goldstein, believe in this idea so strongly that they’ve spent the better part of a decade spearheading a project known as the Perspectives Engine with a simple goal: develop tools that make numbers easier for humans to understand.

Microsoft’s search engine, Bing, delivers millions of facts a day in response to queries. The Perspectives team wondered whether some simple contextual phrases would help people understand and remember their numerical search results.

So they did something basic: Instead of just reporting that Pakistan has an area of 340,000 square miles, they added a brief “perspective phrase,” something like “that’s about the size of 2 Californias.” And then, at time scales ranging from a few minutes later to a few weeks later, they tested people to see if they remembered the fact they had been shown.

Some perspective phrases were better than others. Simpler comparisons from more familiar states or countries led to better memory for the facts. But ALL phrases were better than nothing. Even a slightly unwieldy comparison was more effective than a number alone.
