Think firstTwo well-made websites disagree about wind power's cost

Two polished websites flatly contradict each other about wind power costs. Your first move?

Decide first, then press Next. Watch which box of the ring lights up.

A ring of eight boxes joined by arrows: question, hypothesis, safety review, plan, collect data, analyse, conclude, communicate. After a prediction, the collect-data box is named, then the analyse box. The last step asks which set of sources is stronger for a contested question.

The big idea

triangulate
to check a claim against several independent sources with different interests, rather than trusting one
