I'm looking for a non-vulgar word or short, succinct phrase to describe group behavior wherein all of the individuals are making the same stupid choice. The vulgar "clusterfuck" is close. Acting like "lemmings" has some of the connotations I'm looking for as well.

Example: The other day I drove to pick my son up at school. As usual, there was a traffic jam. On this day, it was made worse by the fact that a dozen people ignored the empty parking spots along the curb and instead waiting in line behind each other, causing a jam which spilled beyond the intersection, blocking traffic on other streets. It was an example of one person after another making the same stupid choice, rather than thinking for themselves. The situation was a real XXXX.

EDIT: As is often the case with English (maybe all natural languages?), the answers have provided multiple ways to say this, with multiple fine shadings of meaning. Thank you all. How do I fairly select only one answer as the answer, when several work well?

    "Mass incompetence" is actually fairly idiomatic.

  • Unnatural languages also offer multiple ways to say the same thing.   I can’t tell you how to choose the best answer, but you can, of course, up vote all the good ones. Commented Feb 15, 2018 at 15:25
  • You choose the one that expressed the sentiment you hinted at in your examples ;o) Commented Feb 15, 2018 at 18:47

You pretty much have it with lemmings, and it's sad that the “vulgar” term says it best.

Polite versions of this might be, depending on context:

and so on.

There are many other anecdotal descriptions, you might benefit from searching for quotations of e.g. Mark Twain (here is a good description of groupthink in other words), or our perennial favourite source of cynical quotes on the subject of intelligence, Albert Einstein (some examples from him and others on the rôle of education in exacerbating these phenomena).

See also this Guardian science blog discussing the negative effects of the “echo chamber”.


You may be able to use Monkey see, monkey do:

the act of mimicry, usually with limited knowledge and/or concern for the consequences.

Other phrases that occurred to me while reading your question are The blind leading the blind:

a situation where a person who knows nothing is getting advice and help from another person who knows almost nothing.

and The inmates are running the asylum:

The people least capable of running a group or organization are now in charge.  Said especially when the result is total chaos or calamity.


The blind leading the blind

is a very old expression of group incompetence. Its earliest known appearance is in Hindu scripture:

Fools dwelling in ignorance, yet imagining themselves wise and learned, go round and round in crooked ways, like the blind led by the blind.

The Upanishad is being taken out of context to a certain extent, but this became a well enough saying to make it into the Gospels:

Let them alone: they be blind leaders of the blind. And if the blind lead the blind, both shall fall into the ditch.

And the saying's appearance in the Bible has led to its becoming a frequent subject of Western art.

The saying is so well known that it's now used for secular purposes, such as death march projects doomed to failure.

  • Yes, “The blind leading the blind” is a very old expression.  Its earliest known appearance on this page is in my answer, which I posted almost an hour before you posted yours. You are of course welcome (and encouraged) to build on other people’s answers, but (IMHO) the courteous thing to do is to reference the answer(s) that preceded yours.    :-)    ⁠ Commented Feb 15, 2018 at 15:27
  • @Scott sorry. I started the answer on my phone and didn't come back to it until several hours later. I wanted some historical background (and a painting, but I couldn't find one that wasn't copyrighted).

I'd call it a "domino effect":

"a series of similar or related events occurring as a direct and inevitable result of one initial event, a cumulative effect produced when one event sets off a chain of similar events.

But from another point of view, I might also call it "mass idiocy" or "mass ignorance"

  • "The situation was a real domino effect" sounds a bit awkward to me.

    @as4s4hetic Yes, it does. One would obviously have to rephrase the sentence.

What is wrong with "thoughtlessness"? Cambridge dictionary: "not considering how your actions or words may upset someone".

    Good word, but... think of clueless as conveying a higher degree of thoughtlessness plus stupidity. I think the OP is looking for something even stronger.

    Missing the collective aspect here, though? Commented Feb 15, 2018 at 1:27

I would use 'gormless' which means having no sense, brainless.


To especially refer to the group and the mess they made or are making, I’d call it a ‘gormless miasma’ or a ‘miasma of gormlessness’.

I understood ‘miasma’ to mean a loose throng of stuff moving around. On looking it up, it seems to mean ‘noxious vapour’, gas, or pong and it is said to mean ‘a contagious power that has an independent life of its own’ which is more what I was thinking, and could be perfect for your dozy group.

A bit like a herd(?) (sorry) of maggots...

It can also mean something like ‘the essence of’ or ‘the feeling of’ as in: ‘a miasma of despair hung over the common room’.
