A Company That Does One Thing Looks Better at It
A pure search page looked more expert than a portal offering weather, sports, and news.
TED · Rory Sutherland: Perspective is everythingMany of Google's early rivals wanted to be portals. The homepage offered a search box, plus weather, sports scores, and bits of news. Google offered almost nothing but a search box, and won.
The explanation, argues Rory Sutherland, a British advertising executive, is not only better technology. It is better psychology. People instinctively believe, in the words of Sutherland, that "something that only does one thing is better at that thing than something that does that thing and something else."
Sutherland calls the pattern "goal dilution." Ayelet Fishbach, a researcher, has written a paper about it. In Sutherland's description, a single, clear purpose reads as competence, while a crowded list of purposes reads as compromise.
That is why a pure search engine could have an advantage before anyone typed a query. The effect predicts that a visitor landing on Google would see one job and assume mastery, while a visitor landing on a portal would see search sitting next to forecasts and headlines and wonder where its attention went.
In Sutherland's phrase, "if you're just a search engine, people assume you're a very, very good search engine." Doing less did not only keep Google focused. In the mind of the customer, it signaled mastery of the one thing it kept.
Questions people ask
Does a specialist actually perform better, or just look better?
Not necessarily. The point is about perception, not performance. A specialist can test worse and still be trusted more, which is why the bias matters in shopping, hiring, and branding.
Does adding features always hurt?
Not always. If the extras seem closely related and do not compete for the same skill, people may see them as a bonus. The problem comes when a product claims several separate goals, so customers wonder where its attention went.
Where else does goal dilution show up?
Restaurants and doctors are familiar cases. A restaurant with a short menu often seems better than one with ten pages, and a doctor who treats one condition can seem more expert than a generalist, even when the generalist is excellent.
