You have almost certainly asked an AI a question and trusted the answer because it sounded calm and complete. Today you put that habit under pressure.
You will read the same factual question answered by two AI tools, weigh what each one is doing, and write a short comparison for your Communication Portfolio. The rule of the lesson is simple: an AI answer is a claim to check, not evidence on its own.
Three ideas drive this lesson:
| Term | What it means for you | Real example |
|---|---|---|
| AI bias. A lean built into an answer by training data or design, not by the facts alone. | Two tools can answer the same question and still pull you different ways. | An AI trained mostly on American pages that assumes you sit the SATs |
| False balance. Giving both sides equal weight when one side lacks evidence. | "Both views exist" can sound fair while hiding that one view is wrong. | A radio debate giving a flat-earth caller equal time with a scientist |
| Verification. Checking a claim against an independent source before you trust it. | You own the check. The AI does not. | Checking a science claim against a textbook before you use it |
The question both tools were asked: Do humans only use 10% of their brains?
AI Tool A
No. The claim that humans use only 10% of their brains is a myth. Brain scans show activity across nearly the whole brain over the course of a day, and injury to small regions often causes serious harm. Neuroscientists do not support the 10% figure. There is no solid scientific evidence for it.
AI Tool B
People have different views on this. Some self-help writers and speakers say humans only use a small fraction of the brain, and that unlocking the rest could boost performance. Many scientists disagree and say we use far more. Both sides appear in books and online discussion. It is fair to present both perspectives until further research settles the question.
Which answer sounds fairer to you, and what does each one do with the 10% claim?
Before you judge the two answers, take a position on what "fair" even means, and say why. This is a warm-up for the comparison you will write later, not the Portfolio piece itself.
These three are practice answers to other questions. You judge Tool A and Tool B yourself in the next step.
