Calibrating certainty

Distinguish observation, inference, likelihood, and firm conclusion without sounding either vague or absolute.

Understand and learn

Work from a natural example to useful language, one small pattern, a spoken attempt, and a response that is relevant to your life.

Aisha

The figures clearly indicate a change in behaviour, although they do not tell us what caused it.

Aisha separates direct evidence from an unsupported causal claim.

Noah

One plausible explanation is that the new schedule reduced unnecessary journeys.

Noah marks his explanation as possible, not proven.

Aisha

That may well have contributed, but it would be premature to treat it as the sole factor.

Aisha accepts likelihood while limiting the conclusion.

Noah

Agreed. What we can say with some confidence is that the change coincided with the new schedule.

Noah states the strongest conclusion the evidence currently supports.

Notice, try, and speak

Understand a natural example and learn a small set of useful words, phrases, and patterns.

Which conclusion stays within the limits of the evidence?

Make it yours

Discuss a claim in English by naming one observation, one plausible inference, and one conclusion that would still be premature.

Use a real trend or change you have noticed, while being honest about what you do not know.
