Assessing the Effectiveness of A/B Testing in the Presence of Network Effects

Instruction: Propose a methodological approach to evaluate A/B tests for a new social media feature, considering potential network effects.

Context: This question challenges the candidate to consider the complexities introduced by network effects in causal inference, particularly in A/B testing scenarios common in tech environments. The candidate should discuss how they would modify traditional A/B testing approaches to account for interactions between users, which might skew the results.
