Hi Tim, I agree, there's a lot of valuable research going on in this space.
As noted in the e-mail, however, this was specifically calling out some of
the research by Googlers to explain how our decision making has been
informed. I apologize it if seemed like this was somehow interpreted as
presenting the definitive source of truth - but I'm also not sure how your
reply is at odds with what was written.
For example, this research that helps explore specific questions that
Google and the Chrome team have explored also heavily cites a large body of
related work, and thus remains an extremely valuable reference for those
wanting to understand the space.
Would you be able to share any of the peer-reviewed papers and
presentations that you think are also relevant?

I'm sorry, I'm really not at all familiar with what you're referencing, and
this isn't in the minutes yet. This certainly seems like it's a
misunderstanding of what was stated, so I'd be happy to help you understand
what was actually said. This is especially important, because it's hard to
tell if your confusion about what was stated is causing active
misrepresentation, and thus we'd love to help you better understand what
was actually stated. I'm hopeful it wasn't your intent, but the way you
phrased it, it sounds like you believe this research also started from
conclusions and worked backwards - but I hope you can see from the peer
review and the papers themselves, this is not a view that is justified or

Thanks for sharing. As I mentioned, this wasn't presented or intended to be
a comprehensive literature survey. As explicitly called out, it was some of
the research that has informed decisions - along with heavy citations for
further relevant reading. Building up a comprehensive survey is no doubt
complex, in part because of the confusion between research conducted with
scientific rigor and peer review, and market research conducted upon one's
