The hard part is letting go of the old idea
Instant photography came from questioning an assumption the whole industry shared. Decades later, the company it built struggled to question its own.
It’s not that we need new ideas, but we need to stop having old ideas.
On a family holiday in 1943, Edwin Land’s young daughter asked why she could not see the photograph he had just taken of her. The question sounds naive, and every adult photographer of the time had an answer ready: film goes to a lab, the lab develops it, prints come back days later. Land treated the answer as an assumption instead of a fact. Within a few years Polaroid was selling a camera that produced a finished print in about a minute.
The chemistry was hard, but the first obstacle was not chemical. It was a belief so widely shared that nobody thought of it as a belief. That is the situation the line describes. The ideas needed for progress are often within reach. What blocks them is an older idea occupying the same space in people’s heads, one that feels like common sense because it has been true for a long time.
For a company, old ideas usually take the form of unexamined constraints. A bank assumes customers must come to a branch to open an account. A software maker assumes its product has to be installed from a disc. A publisher assumes readers pay per issue. Each assumption was reasonable when it formed, and each quietly rules out options before anyone considers them. A useful exercise in any planning meeting is to list what everyone is taking for granted and ask which of those items would still be true if the company were starting today.
Polaroid’s later history shows the principle applying to its own author. Land’s company made most of its money on film, and film shaped how it saw every new product. In 1977 it launched Polavision, an instant home movie system built on chemical film, just as video recorders using magnetic tape were reaching consumers. Polavision failed commercially, and Land stepped back from running the company within a few years. As digital cameras spread in the 1990s, Polaroid still depended on selling film, and it filed for bankruptcy in 2001. The idea that had been new in 1947 had become the old idea by the 1980s.
The line has limits worth stating. Some old ideas are old because they work. Double-entry bookkeeping, written contracts and paying suppliers on time have survived every wave of novelty for good reasons, and a founder who treats every convention as a prejudice will spend a lot of energy rediscovering why the conventions exist. The skill Land’s sentence points at is discrimination: telling an assumption that still holds from one that holds only because nobody has checked.
The corrective is modest and repeatable. When a proposal is rejected because “that is not how it is done”, it is worth asking one more question before letting it go: whether the reason is a fact about the world or a habit of the business.
