This book focuses on the objective and subjective ways in which people arrive at and then act out decisions. The concepts of objective validity and subjective credibility play important roles in this determination.
Objective validity emerges out of rational research-based processes. The word valid is used in two somewhat different ways:
- Valid concepts, conclusions, or measurements are logically or factually sound. They are based on good reasoning, information, or judgment.
- A research instrument or test is considered valid if it measures what it is purported to measure.
- Subjective credibility focuses on a belief that a person who made an allegation about a phenomenon is believable and can indeed be trusted with reference to the allegation.
This book explores the validity and credibility challenges that 21st century students and adults confront as they cope with this flood of information coming from the global reach of the Internet and the rapidly increasing number of television channels and radio stations. Students must learn to recognize the bias that individuals or advocacy groups reflect in their materials.
