Just over a week ago, Google launched a massive change to search personalization, Search Plus Your World. Along with this change came a new toggle switch to shut off personalization.

I actually started with 6 ways to de-personalize, but ended up excluding two of them for the final test (more on that below). The original 6 were:
De-personalization toggle
“pws=0” parameter
Signing out
Signing out + “pws=0”
Incognito (Chrome)
Incognito (IronKey)*
