How can I test if a scroll slowdown agent actually improves my conversion rate?

You can install Seatext's Scroll Slowdown Agent on a subset of traffic or run it sitewide and compare conversion metrics before and after. The agent provides real-time telemetry, so you can see reading dwell time changes. Many users see a reduction in bounce rate and an increase in goal completions within a few days. The free trial allows you to test without risk.
