Die Wissenschaft braucht Meinungsverschiedenheiten. Was macht eine Meinungsverschiedenheit nutzlos?

Vaccine “skeptics” and other science “skeptics” aren’t engaging in scientific debate because they’re ignorant liars arguing in bad faith using motivated reasoning.

There are actual scientific/medical debates about the safety and efficacy of various vaccines. When there were concerns about one of the COVID vaccines during the height of the pandemic, its use was suspended until experts could review the data and determine it was safe. These debates and discussions happen all the time. But vaccine “skeptics” start from the conclusion that vaccines are bad and then cherry pick and spin data to fit that conclusion l.

The same is true of say climate science. There are a lot of unknowns in climate science, but the general concept that human-caused increases of greenhouse gas concentrations in the atmosphere are increasing radiative forcing and thus temperature isn’t really one of them. The actual scientific debates are ongoing, but climate “skeptics” have start from the conclusion that there is no need to regulate greenhouse gas emissions and work backwards to make the evidence fit that conclusion.

The only reason either group is worth engaging at all is because so many people buy their bullshit.
