Every night I argue science live. Here is a year of it, charted.

I am a Ph.D. molecular biologist. At 9 PM Pacific I debate people who reject vaccines, evolution, climate science and germ theory, with the papers on screen. 219 of those streams are transcribed, so you can see what we actually argue about.

Figure 1A. Each column is one transcribed stream (219 streams, 659 hours, Sep 2025 to Sep 2026). Rows are the 8 topics that came up in the most streams. Each cell is shaded by how many times that topic's keywords appear in the stream transcript, on a log scale; cells under 3 mentions stay blank, matching the counting rule. "Shade within topic" scales each row to its own busiest night so quieter topics stay readable; "Across topics" uses one scale for all rows. The right margin shows streams where the topic's keywords came up 3 or more times. Rows are labeled directly, and the lower four swatches are hatched, so color is never the only cue.

Vaccines

Are mRNA vaccines safe?

In the 43,548-person Pfizer trial, side effects were short-term and mild to moderate: sore arm, fatigue, headache. Serious adverse events were low and similar in the vaccine and placebo groups.
