>The word “just” is a signal that you’re not taking their problem seriously.
It wants to use this (flawed imo) reason to make people feel guilty any time they use 'just'.
You don't need to. Just don't use it, and you'll be fine.
(^This is an attempt to provide an illustrative example.)
This is why in some cases it's better to say "Just" instead of trying to hide what you're trying to say in order to maybe be more sensitive without even knowing if that's necessary.
For this situation, I tend to phrase it as "Can we just <x>"? which might be received better than "Just <x>", but "just" is an important word here - I want the other person to understand that I think this ought to be easy. If it's not, I probably want to know why, because that will give me more information about the problem and possible solutions.
If "Can we just <x>" is coming from a trusted colleague who understands the problem space that is exciting because they may have found a shortcut or clever solution.
If "Can we just <x>" is coming from a non-technical client or project manager then I feel nervous because in practice it often indicates that they have underestimated the scope of the problem or we have overestimated the scope of the problem. In some cases it is possible to have enough meetings to level-set expectations but in some cases the "just" seems to be a leading indicator of persistent project tension due to mismatched expectations.
Yes, unfortunately. Along with many other things. Our society has become socially hyper-conscious and that means that anything practical and in some cases observation of reality itself must be sacrificed on the alter of social consciousness.
This is not wrong but it's not always useful. Being more kind in your language when giving help will carry your point across more clearly. Consider a junior engineer stressed out by deadlines -- sure, they should listen to you calmly and fix the problem, but it can be hard when you're not used to the right mindstate. A bit of finesse when choosing your words will go a long way.
This goes the other way too -- ignoring when people use unnecessary language when giving help is for the best, even though in a perfect world they wouldn't. Communication is about being understood, not being fair. Giving a bit from your side to speak on terms the other side is more comfortable on is a great skill to have.
