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 analyzed and considered, which tends to lift its credibility. That is also why a marker should only mark a link you can support.

Before & after

These are fictional teaching examples, not accounts of real events.

Before

“We raised prices. Churn rose.”

After

“Churn rose after we raised prices, and most customers who canceled said they left because of the new price, so the increase likely caused much of the rise.”

When you’ll use it

Root cause analysis: 'Because the server crashed, customers could not check out for two hours. As a result, we took no orders in that window.'

Decision justification: 'Since most complaints were about the hidden save button, we moved it to the top of the page and changed nothing else. Complaints about saving have almost stopped, so the move is the likely reason.'

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

Pro tip

Name the cause and the effect clearly, and use a marker only for a link you can back up.
