If convictions are backed up by best knowledge we have and stand up to scrutiny then they are good until new information is discovered that updates the old. Don’t fall for the ego control, be aware it wants to be right and fights new information, but shouldn’t, learning new things is fun! Follow Sagan’s baloney detection kit, and scientific method, and one part is don’t get attached to a theory. To combine Sagan and Watts, we’re all waves of one ocean, made of stardust, the cosmos observing itself, that’s the truth that sets us free, test it :)

Edit: Convictions are part of Perry’s scheme of cognition, and to get there it requires the skepticism to understand what is peer-reviewed and data backed and what is not.
