A researcher conducted an observational study on consumer decision-making at a local supermarket. The researcher set up hidden cameras near the checkout counters to record customers' facial expressions and purchase choices when presented with impulse-buy items at the till, without their knowledge or consent, to study if age group affects impulse purchases. No debriefing was provided after the observation because the researcher feared participants would demand their video data be deleted, which would bias the statistical sample.
Explain how the researcher should have addressed two ethical issues in this investigation.
