In a few communities I help organize or participate in the internal workings/politics of, I've recently started to critique the fact that we tend to be too liable to pivot our main attention into working on the most recent idea we've had, instead of following through on stuff we were previously working on.
This is, more or less, a form of recency bias. But the issue is that "recency bias" tends to come off as too technical of a term for more casual settings, and I often have to explain the term whenever I use it, robbing it of its usefulness. It's also a little too broad here and results in arguing because we're secretly using different senses of "recency bias" - even if I explain what I mean.
It can either imply the issue above or it can be interpreted as "forgetting previous contradictory feedback in favor of over-correcting to the most recent feedback". The latter is typically not an issue, we're not flip-flopping based on the most recent of e.g. "you're too strict" vs "you're too lenient", we're just prioritizing overall unrelated tasks and initiatives based on the most recent enthusiasm.
There are other terms that immediately come to mind, but are wrong in practice. "Reactionary" has too strong of a connotation of "right-wing/conservative" or alternatively "radical". "Overreact", while not strictly incorrect, tends to confuse people since it implies scope and intensity rather than literally "too likely to rush to prioritize". I tried to invent "overly reactive" but it turns out that it tends to just sound like I'm making a mistake and mean "overreact".
There are a lot of words that are similar: impulsive, hasty, rash etc. But they're just not quite there. I have a feeling whatever this is won't be a single word, but I'm struggling to find just the right term/phrase that's succinct, casual, and likely to be commonly understood (and ideally somewhat precise). I just don't want to be stuck always having to open with a full explanation like "Overly reactive, by which I mean we're too liable to focus [... etc etc]".
