As they do every year, my department is running multiple searches for faculty hires. After all the talks for a given position, the committee solicits feedback on the job candidates.
When submitting feedback on job candidates to a committee is it best to say good things about the candidates you liked and stay silent on the ones you didn't like? Or should I submit comments with both the good and the bad?
Ex. 1 -- Just positive: "Candidate A's talk was impressive in the ways that it does x, y, z. Their work is great....etc." The letter ends there, and I do not mention anything negative about Candidate B
Ex. 2 -- Positive and negative: "Candidate A's talk was impressive in the ways that it does x, y, z. Their work is great....etc. I was less enthusiastic about Candidate B's talk. I found the theory and empirics a bit fuzzy...etc."
The people on the committee are my peers and will assess me in the future through reference letters, tenure letters, informal channels, etc. I am not sure what professional etiquette is for feedback on potential hires, and how negative comments will reflect on the writer.
Note: I am a PhD candidate in political science, although I hope that this questions is relevant to grad students and faculty.
