Claim LD10-HQ-C14 (v1.0)

Research opportunities this claim motivates

What this claim leaves open for research. Each is a hypothesis about a gap, not a finding.

Do AI answers in search cut clicks to outside sites on phones and outside the US?US browsing data show lower click rates on visits with an AI summary, but this is not a causal effect, which is why a randomized replication is needed.
