Irina's translation seems good, but is contradictory and lacks sense.
Generally, the more people you bring together, the less likely they are to reach agreement.

You're very polite, grumbler))) actually the idea by Bernard Show is contradictory. It's a well-known joke which can be translated in different ways depending on what anyone understands or sees there. Only he could know what he meant)))

Grumbler's assessment is correct - this is a pun. Shaw was alluding to reaching (in the physical sense) "agreement" as if it were a palpable place with an actual row of economists' bodies.

to Grumbler: I just can't fathom how something can lack sense and seem good at the same time. ))))

I said "seems good", i.e. "выглядит хорошо" (на первый взгляд)
Was it more correct to say "seems to be good"?

Aleh: you can't fathom how something can be grammatically correct, yet not convey the intended sense?

@ actually the idea by Bernard Show is contradictory. It's a well-known joke which can be translated in different ways depending on what anyone understands or sees there. Only he could know what he meant)))

I disagree.
It is a joke, but not because of a contradiction (I don't see any). And It's pretty clear what he meant.

Your translation doesn't look like a joke and would make a perfect sense without 'even'.

anybody sees what he wants to see)

*Everybody sees what they want to see

to some degree
there are limits, unless your aim is reductio ad absurdum

I was correcting Irina

Uly, thanks, but I meant generally, not (only) in the discussion

That is the general meaning, Irina.

ANYBODY is impossible in this sentence.

ok, thanks)

👍🏼

Actually my first idea was also everybody, but I remembered that you said that "every" means each one of the list)))
why is the first part in sing. and the second one in pl.? As far as I can remember the unit of Murphy's book the verbs can be both in plural...

Yes, in this case EVERYBODY refers to each person in general.

There's agreement, and then there's usage) We use THEY here, and in similar constructions, so that we don't have to choose between HE and SHE, or use both.

with they it's clear, thank you. I meant pl. firm after everybody

Right

Sorry, Irina, I don't understand what do you mean.
