General Discussion

Coupled with what happens in the vast majority of instances - the OP doesn't (sometimes actively refuses) to correct the misinformation - and people contribute to respond to the OP (and spread it) as if the fact checking never happened.

When it happens, and the person being fact-checked is receptive, it's a good thing. I've seen a few examples here recently. But most of the time, it doesn't - and what people take away is the incorrect information, rather than the correction. As appears to have happened here with the memory of the original images.

I didn't know what the solution is, but it is a significant problem. The only thing I can come up with is people making an individual commitment to fact check before they post, to make corrections when they realize they weren't factually accurate, and to read beyond the headline and fact check each other. Not likely to happen in this instant gratification and race to be the first to post world. But I'm not convinced it can be externally imposed in any effective manner.

Bottom line we have to care about facts, and to many of us put that second, third or even last when considering posting something.
