Use because, therefore, so to show causal links.

What & why

What it is
Words and phrases (because, therefore, so, since, as a result, consequently, due to) that explicitly tie an action or condition to the outcome it produced, naming the causal direction rather than leaving listeners to assume it. They turn a loose pairing of facts into a stated chain of reasoning, making clear which event is the cause and which is the effect. This matters most when a sequence could otherwise read as mere coincidence or be linked to the wrong driver.
Why it works

People look for reasons behind events almost automatically, and a stated cause satisfies that pull better than two facts left side by side. Words like because and therefore name the link explicitly, so listeners do not have to test whether one thing actually drove the other; the connection is given, which lowers effort and reduces the chance they pair the wrong cause with the wrong result. Marked causation also reads as reasoning rather than coincidence, making a claim sound analysed and considered, which tends to lift its credibility.

Before & after

Before

“We raised prices. Churn rose.”

After

“We raised prices, therefore churn rose.”

When you’ll use it

Root cause analysis: 'Because the server crashed, we lost 2 hours of sales. Consequently, revenue dropped 15%.'

Decision justification: 'Since user feedback was negative, we redesigned the interface. As a result, satisfaction improved.'

Project retrospectives: 'Due to late requirements, we missed the deadline. Therefore, we're implementing earlier stakeholder reviews.'

Pro tip

Name cause, then name effect, in that order.
