Trouble is, people tend to forget they are domain experts. I trust my doctor for medical advice, but I don't consider them any more competent to dispense legal advice than a random acquaintance. However, it is common for highly-competent people in a domain to feel they are more qualified than average in other domains (which is a trait I actively work to control myself). Software devs seem very susceptible to this, since a large part of the field involves being able to quickly learn enough about a subdomain of knowledge to implement a required solution. I'm no expert statistician, but I have implemented multiple projects that required knowledge of statistics. However, I'm just at the point of "knowing what I don't know", while I haven't studied enough classical mechanics to truly grasp how much I don't know. So while I feel I have a good working knowledge of statics, asking me to design a bridge would be foolish. Sure, I may think I 'could' design a bridge, but that is just folly.
