A reader wonders:
What do you do if you and one of your advisees share outside interests that bring you into social contact off campus, and some of these interactions might affect your advisor-advisee interactions on campus?
That is, what if an advisor and an advisee (think: grad student, but could also be undergrad or postdoc) have a hobby or other outside interest in common and see each other frequently outside of work/campus? Perhaps these interactions are quite positive -- perhaps advisor and advisee become friends outside of work, owing in part to these shared interests.
Is there a problem?
There might be. I haven't been in this situation as an advisor, but here are some related questions for discussion, formulated based on additional information in e-mails I have received on this topic:
Does the beyond-campus interaction/friendship affect the advisor-advisee relationship in some ways that are unfair to other advisees?
It could, but I think there are ways to deal with any perceived inequity arising from external interactions with some (but not all) advisees, much as we advisors (should) deal with perceived issues related to the fact that it's normal to enjoy conversing with some advisees more than others. Perhaps with some students, all conversations are restricted to research and other academic topics, whereas with others, conversations may range widely to politics, movies, cats etc. As long as we are alert to the situation and are careful to be equally accessible and supportive of all advisees, this should not be a problem
As a grad student, I had some low-level anxiety that my grad advisor's shared interests with other advisees in certain outdoor activities (in which I did not participate, but they all did together) made him like them more, and that this would color his overall opinions and therefore his letters of reference.. but in the end, there was no reason to worry.
What about the dynamics of the advisor and advisee who share an outside interest? If you are sort-of friends off campus, do you switch off that aspect of your interaction when on campus?
This is where it will be useful to have reader input, as I have not encountered this myself. I can imagine that it could be awkward if you know something about your advisee's personal life -- maybe they are having a crisis, for example -- but you aren't sure whether to acknowledge this on campus, or pretend you don't (really) know because you don't necessarily have this level of knowledge about your other advisees.
A (too) simple answer would be to say that we advisors should just do our advisor-jobs the same way, whether or not we know the details of our advisee's personal lives and even whether or not we like them, and provide whatever professional support is necessary and appropriate in our role as advisor. More difficult would be deciding whether/how to use 'outside knowledge' of an advisee's emotional state when providing (or withholding) criticism of an advisee's work. If you know that an advisee is having personal problems, for example, should you hold back or behave as you would without the additional information/insight?
Speaking from inexperience, I would say to put on your advisor hat and have the professional conversations you need to have with your advisees about their work. Even though you might know that you will likely upset a fragile or sensitive student with criticism (however kindly worded), or you might suspect that you will harm your beyond-campus friendship with an advisee (by exerting your authority as an advisor), you aren't doing an advisee any favors by withholding feedback about their work. If you give a struggling student advice that is constructive -- e.g., here's what you need to do to improve, and here are some suggestions and guidelines (perhaps to be worked out more fully in discussion) -- this might help the student more than if you tread lightly around them, not wanting to upset them.
But that's easy for me to say -- I am not in that situation. So, I am interested to hear from those who are: advisors and students.
