The creative parable of the 100 light bulbs

A creative director recently shared with me the parable of the 100th light bulb. It goes like this:

When you turn on the first light bulb in a dark room, the effect is transformative. Where before there was only darkness, now there is light. But by the time you switch on the 100th light bulb, the incremental difference is so small that nobody notices. The lesson is that there’s a point of diminishing returns where it’s not worth the effort to keep exploring new ideas.

I disagree.

For one thing, if your project is a web page or an email, turning on the light bulb is so trivial a task you shouldn’t give it a second thought. Through multivariate testing, marketers can not only turn light bulbs on and off, but move them around at will to see if one arrangement is better than another.

But beyond that, turning on the 100th light bulb is what we as creatives are paid to do, assuming we charge more than the journeyman copywriter who can take a brochure and turn it into a sales letter.

In the heyday of subscription direct mail, the 1980s and early 1990s, writers like Bill Jayme and Linda Wells were paid tens of thousands of dollars (1980s dollars) to produce circulation promotions that, if they were successful, might increase response rate by a microscopic fraction of 1%. But because the numbers mailed were so large, it was a savvy investment by the publishers.

I myself once wrote an ad that appeared in Computerworld, for a long departed agency and software client. They marketed primarily through direct mail, but some targets just didn’t ever respond. This ad won a new account from one of those targets, and the value of the business was such that it paid for the entire cost of the ad, including media, for the life of the campaign.

Was that worth the 100th light bulb? I think so.
