What is a high journal impact factor?

Nature has an IF of ~65; Science ~63; New England Journal of Medicine ~100+. Top-tier discipline-specific journals: Lancet ~200; Cell ~66; JAMA ~120. Average IF across all Clarivate-indexed journals is approximately 1.5–2.5; most journals are below 5.

What are the criticisms of impact factor?

JIF can be gamed by self-citation policies, is skewed by a few highly cited papers, varies enormously by field, rewards review articles over original research, and does not measure individual paper or author quality. Many researchers advocate replacing it with CiteScore or article-level metrics.
