You are correct about the first name, I had forgotten that part.
And it's a big problem, as I pointed out. Think about all the information you could get from a name plus some general knowledge about the decades in which the name was popular or unpopular:
- gender
- decade (or at least era) of birth
If the mediums knew the parameters of the experiment, then they can combine that to make a very good guess at which is that particular case.
There are parameters of the study that the mediums may have known without violating the blinding:
- the sitter is an undergraduate student
- the sitter attends the University of Arizona
- the sitter had a close relationship to the deceased
- the deceased is either the parent or peer of the sitter
So say you guess that the person is a peer. You now can say with relatively good accuracy that the deceased:
- probably grew up in Arizona, or at least the southwest.
- died shockingly young
- probably died in a way that was considered unexpected and especially tragic
- probably died without having kids
- (assuming
general knowledge about causes of death in young people), probably died from some sort of injury.
- growing up, involved themselves in the pastimes and pop culture of the late 1990s and early 2000s (remembering that the paper was published in 2007, so assume that the research was done in 2006 and the deceased was born around 1996 or so).
Or say you guess that the person is a parent. You now can say with relatively good accuracy that the deceased:
- probably either grew up in or moved to the Southwest.
- was of the right age to have a child who was an undergraduate student (so probably 40-50 when the research was done, so born about 1956-1966).
- died in their 30s or 40s (since they're now deceased, but lived long enough to have a close relationship with their child).
- probably died from some sort of injury, but cancer or coronary issues would be a close second.
- either wasn't divorced or had a significant amount of custody (again: close relationship).
- growing up, involved themselves in the pastimes and pop culture of the 1960s and/or 1970s.
- as a parent, probably involved themselves in the pastimes of their child (so pick the typical pastimes for a child and you have a good guess at their hobbies in the eyes of their child).
- was well-off enough to send his or her kids to the University of Arizona.
- maybe involved themselves in hobbies that go along with having a disposable income (e.g. golf).
- (if the parent was a woman) either didn't work, or worked and struggled with workplace discrimination issues during her working life.
None of it's iron-clad, but we aren't talking about iron-clad. The average score for the "intended" group was 3.56, so all we're talking about enough information to get a rating between
"3: Mixture of correct and incorrect information, but enough correct information to indicate that communication with the deceased occurred" and
"4: Good reading with some incorrect information" in a group of people who were screened from the outset for their willingness to believe that this sort of communication is possible.
Do you think this is enough information to bump the "intended" group up a bit? And that's all only from a first name.
