Anti-science sentiment is everywhere, but Canada is standing firm: #ScienceMatters! Great to see this statement and its signatories. scienceupfirst.com/sciencematte... @caulfieldtim.bsky.social

#ScienceMatters.

Important to clearly counter demonstrably false bunk. Broad consensus that:

- Vaccines do NOT cause autism
- Ivermectin NOT effective against cancer, covid, etc
- COVID vaccines do NOT cause "sudden death" or "turbo cancer"

AI “safety measures” leave much to be desired. The authors found that chatbots refusing disinformation (ex: “I cannot assist with creating false information") can be tricked simply by wrapping requests in innocent frames like “simulation.” theconversation.com/how-we-trick...

People with cancer are already carrying enough. Ending a harmful practice that adds to their burden shouldn’t be up for debate. Thank you to co-authors @srmarcon.bsky.social @spidermaani.bsky.social @maizie333.bsky.social @caulfieldtim.bsky.social @kenworthy.bsky.social Greg Hartwell.

How Google search ads work: advertisers, like alternative cancer clinics, can choose to show their ads when users search specific phrases. When it comes to cancer, this means sensitive searches ("terminal cancer treatment") can be met with potentially exploitative ads.

This is but one example of a larger issue (this does not happen only for cancer). Google search ads enable advertisers to exploit users’ searches for information. Google should urgently prohibit keywords targeting the sensitive information queries of medically vulnerable groups.

We find advertisers mimicked the sensitive queries of cancer patients to target them with their marketing using Google’s keyword-matching feature. In 2023, 20,035 unique keywords emulated Google searches seeking information on the themes below.

Google search ads allow advertisers to select keywords/phrases which are then matched to the searches of Google users. See below an example of a fake ad I set up & how I could theoretically target my ad to Google searches seeking cancer information.

When anyone searches for information on cancer treatment options - they shouldn't see ads for scientifically unsupported treatment or ads targeting people who have exhausted their treatment options. Our new study (unfortunately) finds this is occurring misinforeview.hks.harvard.edu/article/goog...
