a room where you shout your opinion and it comes back louder, wearing a costume of consensus.
means an environment, often social or digital, where people only encounter beliefs that match their own, amplified by agreement and stripped of friction.
from literally an acoustic chamber built to bounce sound back on itself, borrowed since the mid-20th century for media and social bubbles that do the same to ideas.
