Art critic: Nowadays, museum visitors seldom pause to look at a work of art for even a full minute. They look, perhaps take a snapshot, and move on. This tells us something about how our relationship to art has changed over time. People have become less willing to engage with works of art than they once were. The art critic's argument depends on the assumption that ['visitors would enjoy their museum experiences more if they took more time with individual works of art', 'the amount of time spent looking at a work of art is a reliable measure of engagement with that work', 'museum visitors who take snapshots of works of art rarely look at the pictures afterward', 'museum visitors today generally look at more pieces of art during each museum visit than museum visitors looked at in the past']
