yes, the easiest way to spot scientism is to look for value statements being conflated with factual statements. This is done unintentionally in many cases, the persuaders can’t help it because they can’t distinguish between the two.
1) you falsify the data that someone thought was factual that they used to support their values. They take this as an attack on said values.
2) you point out errors in the train of logic between factual statements and values, and/or point out that there is no valid logic train between their values and facts.
3) you make a factual statements and it is confused for a value statement. This happens because we’re taught to value truth and this valuation occasionally glitches. People assume that because you say something is true that you are also saying that it is good.
4) vice-versa of the above. you make a value statement and people take it as a factual statement. this is the goal of a persuader.
I’m sure there are other common examples.
