I almost always consider that anything may not be true, and I am definitely considering it whenever I use the verb "may" ;)

More than speculation, my concern was Andrej's report that clearing cookies was not enough, or whether you or anyone knows for a fact if it's false or true, or any additional test people may do to shed light. Specially since most mechanisms used by most search engines have secret elements in this aspect -- the Wikipedia article on filter bubbles does not provide any information about the mechanisms, just the effects.
