True. However, relating this back to the software industry, I have often found myself in conversations where somebody says "according to so-and-so / this blog / this author, we should be doing this" - I feel like we don't really know what we are doing with software in the grand scheme of things (although things are getting better) thus many in the industry fall back on the ol' argument from authority. It seems to hold its weight in conversation in my experience. This is bad, everyone's opinion should be questioned and doubted.
