There’s nothing wrong with just suggesting reasonable ideas that might be useful. If everything needs to have a solid evidence base or rigorous supporting arguments before we talk about it, it becomes too easy to shut discussion down prematurely without ever discovering whether an idea does have value for someone, particularly in an industry like ours where much of what we do is hard to measure objectively. It’s helpful to be clear about whether an idea being presented is just someone’s personal thoughts or anecdotal experience or whether it does have a stronger foundation. If something is presented as a firm recommendation of good practice then it’s fair to expect the latter. But it’s also dangerous if we reflexively disregard any idea that doesn’t already have robust evidence behind it.
