Second Edition Changes

The original “A Practical Guide to Critical Thinking” was hosted here beginning in 2004. Since that time it has become internationally adopted or referenced by educational institutions, medical institutions, militaries, government agencies, blogs, and newsletters as a handy guidebook on critical thinking.

This second edition, now available at a modest price, has been updated to include a new appendix on hindrances due to natural biases (Appendix 5). Additionally, the entire guidebook has been reformatted as an eBook. As such, the tables of critical thinking hindrances have been converted to appendices to make them legible on various reading devices.
