Statement of Conversion

Description:  Accepting the truth of a claim based on a conversion story without considering any evidence for the truth of the claim.

Logical Form:

I used to believe in X.

Therefore, X is wrong.

Example #1:

I used to be a Christian, now I know better.

Explanation: All this tells us is that the arguer changed his mind.  We don’t know why. Accepting this as evidence against Christianity would be fallacious reasoning.

Example #2:

There used to be a time when I didn’t believe, now I see the light and have accepted Jesus as my savior!

Explanation: All this tells us is that the arguer changed his mind.  We don’t know why.  Accepting this as evidence for Christianity would be fallacious reasoning.

Exception: It might be the case where the person with the conversion story has some expertise or direct experience related to the claim, so their conversion story is reasonable evidence for the truth of the claim.

I used to think that the earth was flat, then Elon Musk took me to the space station in one of his ships. I am no longer a flat-earther, and I can’t believe what an idiot I was listening to YouTube videos of 40-year-old guys living in their parent’s basement over NASA.

Tip: Remember not to confuse people’s interpretations of their experiences as actual experiences. People who were unbelievers in aliens visiting earth and changed their mind based on “aliens visiting them in their dreams” are almost certainly misinterpreting their experiences.

Reason: Books I & II

This book is based on the first five years of The Dr. Bo Show, where Bo takes a critical thinking-, reason-, and science-based approach to issues that matter with the goal of educating and entertaining. Every chapter in the book explores a different aspect of reason by using a real-world issue or example.

Part one is about how science works even when the public thinks it doesn't. Part two will certainly ruffle some feathers by offering a reason- and science-based perspective on issues where political correctness has gone awry. Part three provides some data-driven advice for your health and well-being. Part four looks at human behavior and how we can better navigate our social worlds. In part five we put on our skeptical goggles and critically examine a few commonly-held beliefs. In the final section, we look at a few ways how we all can make the world a better place.
