Welcome back to the Atheist Experience. This week, Matt Dillahunty is joined by Genevieve!First up is Manuel from Puerto Rico who wants to know what our hosts think is the best way to educate yourself and others about critical thinking. The first step is recognizing where we are suspending critical thinking, and then going back through and asking questions that put that previously accepted idea on trial to see whether the belief was truly justified.Next is Setuf from Spain who asks our hosts what the difference is between Speciesism, Racism, & Sexism. All three are biases that are each relevant to the level that they operate at (e.g. Species, Race, and Sex/Gender).Next is Steven from WA who would like advice on how to discern good sources of truth from sources that may have undisclosed conflicts of interest. If we use Matt’s definition of “truth” in that it comports with reality, then we can look at a source’s track record, their own testing data (if available), as well as any other peer-reviewed sources they used to justify their statement. The truth is unlikely to be found in its entirety within one document or source, so getting multiple quality opinions or sources may help build a better picture.Next up is Joe from OH who thinks Matt is wrong about Doyle’s Fallacy. How do we know that we’ve actually eliminated all other possibilities? Just because something is unlikely doesn’t automatically eliminate it from consideration.Up next is Allen from MI who claims that science as a tool cannot investigate God and other non-physical phenomena. Unless we have another tool that allows us to reliably investigate the non-physical, we are not justified in accepting the existence of such phenomena if we actually care about the truth.Next is Michael from CA who believes that free will exists. The topic is complicated, as evidenced by the nearly continuous debate on the subject, as it is often difficult to determine the influences on our decisions such as indoctrinated beliefs, societal culture, and environmental circumstances.Up next is Simo from Canada who asks our hosts if they are compatibilists or “hardcore” determinists. Varying forms of determinism, hard or soft, are true across various definitions of free will. Compatibilist arguments only assert that determinism and free will can both be accepted without being irrational.Our last caller is Aaron from AR who would like advice on setting boundaries with religious family members. Being honest and upfront with family can be tricky to navigate, especially when trying to prevent an escalation. You have just as much right to set the ground rules for their behavior when it comes to raising your child just as they do when it comes to their own.
