We make new discoveries as time progresses. One experiment is set up and it’s results interpreted differently than another.

Now I don’t mind this and choose to believe the most recent credible findings. But I do understand when people see this as flip-flopping or maybe even contradicting.

I don’t like to admit it, but I also understand why that doesn’t particularly bolster trust.

I do not doubt scientific method, I doubt people's ability to carry out scientific method correctly and without bias and agenda.

Relative number of lies/media sensation is inversely proportional with trust. Solution, reduce corruption, sensational news and lies.

Note: Sorry about unrelated root topic, I remembered a scientist attending "Global Challenge Competition" asking "Why people nowadays more and more mistrust authorities..."

None of those statements are scientific and scientists don't talk like that, so the onus falls squarely on politics and media. And laypeople. People consume a ton of knowledge from their peers, even before social media.

Each of those points has enough nuance to fill volumes of research papers.
