i trust doctors based on vibe
the middle aged doctor who was eating yogurt with his finger: trustworthy
the young doctor who has very neat handwriting and seemed very concerned about side effects: trustworthy
the middle aged doctor who made me wait for every appointment and wanted me out of her office as soon as possible: not trustworthy
the old doctor who struggled to even hear me: not trustworthy
the middle aged doctor who told me i don't drink enough alcohol: trustworthy
but also, rule of thumb is to check multiple docs when something has the possibility of being serious
