Decision

Stop deciding on 'I think'

Experience is too valuable to discard — and too dangerous to become proof without investigation.

"I think" gets a bad rap.

It tends to appear in data presentations as the villain of the story. On one side, the intuitive manager. On the other, the scientific organization, surrounded by charts and numbers.

Real life is not that tidy.

The experienced manager sees things the database has not seen yet

Someone who works twenty years in an operation learns to perceive signals.

They know when a customer is about to give up. They sense that a particular supplier is going to be late. They recognize a project that started losing momentum before the official timeline admits it.

This has value.

Experience is a pattern recognition machine.

The mistake is not having intuition.

The mistake is ending the investigation at intuition.

Intuition should open a process

"I think Wednesday sells better."

Great. We have a hypothesis.

Now we can ask:

  • better in revenue or in margin?
  • in the dining room or in delivery?
  • at what time?
  • with which product mix?
  • with or without a promotion?
  • does it happen every week or was it a specific period?

Notice the change.

The phrase stopped being a conclusion and became a door.

This is exactly what a data-driven culture does with experience: it does not discard it; it transforms it into investigation.

Evidence can also be wrong

There is another common exaggeration: imagining that a number ends the conversation.

It does not.

Data can be wrong. Comparisons can be poor. A correlation can be treated as causation. An indicator can be measuring the wrong thing with great precision.

For this reason, it is not about replacing people with numbers.

It is about improving the conversation between perception, evidence and decision.

The phrase I prefer is not "stop using your intuition".

It is simpler:

Exchange part of "I think" for "let's find out".

Evidence

Do data-driven companies perform better?

Yes, there is an advantage — but it shows up when data changes decisions, not when a company buys tools. What 15 years of studies and the 2026 surveys say.

The construction site started generating data

Chinese robots that paint, sand, level concrete and scan the site arrived in Brazil. To work, they need one thing above all: data.
