Do you know who “they” are? You must, because you’re constantly referring to them in the same way I do and many of us do. Each time we are trying to emphasize a point, we find ourselves referring to what “they” say or how “they” view that situation.
“They” say that coffee is bad for you but “they” also say that coffee has proven health benefits. Who do you believe when both views are what “they” say? We often refer to “they” when we want to state our view, even if we’re not sure “they” said it. I suppose there are two truths to take from the use of the word “they” – one is that it likely means we don’t have all the facts about a given topic and the other is that we might not have the courage to hold our ground on what we believe. Apart from the casual use of the word, these two points might actually be the reason behind the reference.
It’s important to have our facts straight, especially when others are dependent on our work and input. Others will respect you more if you share your view and position constructively even if “they” don’t agree or aren’t around to back you up.
Perhaps a better approach than saying “they” is actually saying “I believe” or “I think”…
