Instinct vs evidence: how to strike the balance?
Product decisions are rarely made on data alone. They sit somewhere between instinct and evidence.
Ideas come from experience. From understanding the market. From knowing what has worked before. At a senior level, that instinct is valuable. It helps teams move quickly and provides direction when there isn’t perfect information.
But relying on instinct alone is where things start to go wrong.
The role of instinct in product development
Instinct isn’t the problem. In fact, it’s a critical part of good product leadership.
CPOs and Heads of Product build experience over time. They understand their users, their product, and the commercial priorities of the business. They’ve seen patterns, tested ideas, and developed a sense of what might work.
That kind of judgement allows teams to move forward without getting stuck in analysis. There is a time and place for it.
Why product decisions default to opinion
The challenge is that, in reality, instinct often becomes the default.
Decisions are influenced by:
ideas coming from CEOs or senior stakeholders
confidence in personal experience
internal politics
time pressure to move quickly
Under those conditions, it’s easy for opinion to outweigh evidence. Not because teams don’t care about users, but because the environment makes it difficult to slow down and validate thinking. There’s often a belief that these decisions are strategic. But in many cases, they’re closer to educated guesses.
Experience can make those guesses more informed, but without evidence, they’re still guesses.
The impact of product decisions without evidence
This is where the impact becomes visible. Features are built based on assumptions that haven’t been tested. Sometimes they land. Often they don’t.
When they don’t, the cost shows up quickly:
rework
wasted budget
time spent building the wrong things
low adoption and engagement
And by that point, the team isn’t moving forward. They’re fixing.
Why evidence isn’t used consistently
Most teams understand the value of evidence.
So why isn’t it used more consistently?
Time pressure is a big factor. Research and validation can feel like something that slows things down. When there’s urgency, it’s easier to move forward with what feels right than to pause and test it. Access is another challenge. Not every team has the tools, processes, or support to gather meaningful insights quickly. And sometimes, it comes down to confidence. When leaders strongly believe in a direction, it can feel unnecessary to validate it.
All of this makes instinct the easier option.
How to balance instinct and evidence in product strategy
The goal isn’t to remove instinct from decision-making. It’s to balance it with evidence. Strong product teams use instinct to guide direction, but they validate those ideas before committing fully.
They:
test assumptions early
involve users in the process
use evidence to prioritise what matters most
This isn’t about slowing down. It’s about making sure effort is focused in the right place. Because when you get that balance right, you don’t just move faster.
You move with more confidence.
Why this matters for business outcomes
This isn’t just a product challenge, it’s a business one.
When decisions are grounded in both instinct and evidence:
teams focus on the right features
rework is reduced
budget is used more effectively
products see stronger adoption and engagement
It creates progress that is based on confidence, not guesswork.
A better way to think about it
Instinct and evidence aren’t opposing forces, they’re complementary. Instinct gives you direction, evidence gives you confidence.
The strongest product organisations don’t choose between them. They use both.

FAQs
-
A: The strongest product decisions use both. Instinct provides direction based on experience, while data and evidence help validate that direction and reduce risk.
-
A: Yes. Instinct is built through experience and understanding of users and markets. It helps teams move quickly, especially when there isn’t complete information. The challenge is ensuring it’s balanced with evidence.
-
A: By using instinct to guide ideas and direction, then validating those ideas early through user research, testing, and feedback. This helps teams move quickly while staying aligned with real user needs.
