Ideas should earn their place

Marketing needs ideas, instinct and creative ambition. What it does not need is a system where the first exciting idea in the room automatically becomes the strategy.

An idea is allowed to start as an idea

There is nothing wrong with somebody saying, 'We should try TikTok', 'We need an app' or 'What if we completely changed the campaign?' Creative leaps often begin before the evidence is tidy. The mistake comes later, when enthusiasm is quietly promoted into certainty and the organisation begins building a business case around an answer it already wants.

A stronger process keeps the idea alive while asking what would have to be true for it to work. Who would it help? What behaviour might change? What evidence suggests the problem exists? What would success look like, and what is the cheapest credible way to test the assumption before making a much larger commitment?

Instinct can generate hypotheses

Experienced marketers build pattern recognition. Founders notice unmet needs, sales teams hear recurring objections and creative people see opportunities others miss. Those instincts are useful, but their best role is often to generate a hypothesis rather than declare a fact.

This is where a simple distinction helps. Evidence is what can reasonably be supported. Observation is something noticed that deserves attention. Hypothesis is the proposed explanation or prediction. An idea can be a very good hypothesis without pretending it has already been proven.

Scale the evidence to the decision

Not every choice requires a six-month research programme. A £200 advert that can be switched off on Friday should face a lower burden of proof than a £120,000 rebrand that will shape the organisation for a decade. The cost, risk and reversibility of the decision should influence how much confidence you require before committing.

That balance protects marketing from two bad extremes: reckless certainty and research paralysis. Ideas should not be suffocated by evidence, but they should earn the right to consume serious time, money and organisational attention.
