Summary of "Evidence based reasoning"

Concise summary

The video (part of a playlist supporting the book Apprenticeship Behaviors: Mastering Essential Thinking Skills) explains evidence-based reasoning: forming decisions and arguments using objective evidence (facts, data, reliable sources) rather than opinion or bias. It emphasizes why this skill matters in the workplace and gives practical steps to develop it.

Methodology — step-by-step instructions

Ask questions about information you receive
- Who produced this information? What is the source?
- Is the source credible and relevant?
- Are there potential conflicts of interest or biases?
Gather relevant data before deciding
- Collect facts, statistics, research studies, and multiple independent sources.
- Prefer primary, peer-reviewed, or otherwise reputable sources over anecdotes.
Analyze the evidence carefully
- Look for patterns, trends, and inconsistencies.
- Assess the quality, relevance, and sufficiency of the data.
- Consider the methods behind studies or data (sample size, controls, methodology).
Consider alternative explanations
- Don’t rely on a single piece of evidence; generate and evaluate competing hypotheses.
- Test whether other explanations fit the data as well or better.
Be willing to change your mind
- Update conclusions when new, credible evidence emerges.
- Avoid commitment to a conclusion purely for consistency or convenience.
Practice regularly
- Apply these steps in everyday decisions and workplace problems to build competence.
- Reflect on outcomes to improve future reasoning.
