WHAT THE CLIP SHOWS
Pause before accepting the conclusion
What information would you want before relying on this demonstration?
INTERACTIVE LESSON 06
Does this demonstration prove the claim?
Pause, look for missing context and choose a conclusion the evidence supports.
Fictional teaching examples. These scenarios do not describe tests of real products. Missing evidence is a reason to ask questions, not proof that a product fails.
Which conclusion is justified?
Ask for a fair comparison
Identify the claim, record the conditions and look for evidence that actually answers the question.

The number drops
A presenter adds a shield. The meter display falls.
Context: The camera also shows the meter being moved farther from the source.
Two things changed, so this demonstration cannot isolate the effect of the shield.
Ask: Repeat with the same position, orientation, mode and source activity; change one thing at a time.
The display shows zero
A clip shows a zero on the meter after a product is introduced.
Context: The clip does not identify the instrument, mode, frequency coverage or detection limit.
Zero on an unidentified instrument does not establish that every field is absent.
Ask: Ask for the instrument details, units, selected mode and measurement limits.
One call fails
A phone in a pouch does not receive a call.
Context: Only one connection attempt is shown, with no details of other wireless services or repeat checks.
This observation does not establish blocking across every service or frequency.
Ask: Ask for relevant finished-product test results and a repeatable verification procedure.
A testimonial sounds convincing
A customer says they slept better after buying an accessory.
Context: No comparison group, controlled conditions or assessment of other changes is provided.
An individual experience does not establish that the product caused the improvement.
Ask: Look for evidence addressing the specific product and claimed outcome, rather than relying on the testimonial alone.
Sources and scope
FTC health-product evidence guidance discusses support for health claims and the limitations of testimonials. It does not assess the fictional products in this lesson.
