Questions we anticipate getting:

But no one reads disclosures? What were all of the correct answers, anyways? Have disclosures been updated since publication? What should disclosures say?

Notes from Blase

make title slide look like private mode disclosure include universities start with motivation

  • people have misconceptions about private browsing mode
  • all major browsers have private mode, meant to be local
  • some limited prior work on misconceptions
  • our main research question: browsers differ by how they

explain what private mode does

  • show real disclosures, show 3 different ones in full page;

maybe mobile versions

  • to what extent do the disclosure impact whether people have

misconceptions

  • no citations

“previously documented misconceptions” survey methodology

  • keep main lines, remove dots

move the walk through to right before 460 participants

  • maybe flip; abstract or example

results

  • participant demographics: as briefly as possible, more graphics;

separate reasons and usage

  • drop reasons for using
  • start with the scenarios, confidence/which disclosure did best at the

end

  • 4 types of scenarios —> remove org slide
  • make axes bigger, explain how to read the slide (incorrect answers)
  • no graph for non-misconceptions
  • show blank graph, then insert data
  • separate distinguishing and comparative
  • “overestimated protections”
  • have quotes in notes

implications/discussion

  • less words
  • screenshot of disclosure language and show the logo of each

browser how do the disclosures impact misconceptions

  • at beginning of results: show results for disclosures in aggregate
  • then specific disclosures at the end
  • meaninglessly vague control, read it outloud; see how the other
  • nes compare
  • scale of how many they got right
  • misconceptions that disclosures particularly emphasized

end on key takeaway slides, and contact info, pictures of coauthors
