Tell apart a real disagreement and a manufactured balance.

The airtime is split evenly. Nothing here says whether the evidence is.
A report on a measurable question gives equal time to one specialist who agrees with the evidence and one who rejects it. What has the reader been told?
Yes.Airtime is read as weight. Splitting it down the middle makes a factual claim about the state of the evidence — usually without anybody noticing they made one.
Not quite.Fair to the two people. The reader is not choosing between two people; they are trying to work out what is true.
Not quite.The reader judges using the layout they were handed. Equal time is part of that layout.
Balance is a rule about voices. Accuracy is a claim about the world. When a question has a measurable answer, the two can pull apart.
Which of these questions can evidence settle, and which are genuinely arguments about values?
Has average sea level risen over the last century?
How much should this generation spend to protect the next?
Does this drug lower the death rate in the trial?
Is a shorter working week worth a lower income?
How many people live in this district?
Yes.Two-sided coverage is right for a values question and misleading for a measurement. Much of the fiercest argument happens because one side is answering the first kind and the other the second.

In proportionThe dissent gets a mention, not a chair. Honest about weight, and it can bury a minority that turns out to be right.
Which arrangement tells the viewer the most while costing the least?
Yes.One sentence carries the information the layout cannot. It keeps the dissenting voice audible while stopping the format from making a claim nobody checked.
Not quite.It hides the one fact needed to decide: how many people who have looked hardest at this hold each view.
Not quite.It is the most honest about weight, and it is also how a lone dissenter with the better argument disappears. Every consensus that later broke was once three people.
Move the control to see what changes.
A campaign group offers a spokesperson for every broadcast on its issue, at any hour. How does that change the coverage?
Yes.Being reachable at 6:40am is a strategy, and a cheap one. A view held by very few people can be present in almost every discussion of the subject.
Not quite.They try to. Under deadline, the person who answers the phone wins the slot.
Not quite.Audiences rarely see who declined. Repeated appearance reads as standing.

The false impression is produced by the fairness rule, not in spite of it.Yes.Nobody in that chain has to be dishonest. A booking rule meant to prevent bias produces a false picture of the evidence, and the rule is the reason it works.
You see a debate between two people on a factual question. What is the one thing you should look for before weighing it?
Yes.Without that line you are being asked to judge a measurement contest on presentation. With it, you can hear a minority view and still know it is one.
Not quite.Confidence is a performance skill, and it is inversely related to how much a careful person will claim.
Not quite.Useful, but a single qualification is a weak signal — there are credentialled people at the far end of almost every question.
Lesson complete
Equal airtime is a claim about the evidence that nobody checked.
