The outside view
Self-report has a blind spot with a known shape, and another person can see it.
The self–other knowledge asymmetry finding is that you are the better judge of your internal states, and other people are the better judges of your observable and evaluative traits. Neither of you is the better judge of everything. So for questions about how you come across, an informant is a better instrument than your own memory.
A protocol
Send this to two people who have seen you work or live closely for more than a year. Ask them to answer in writing, not in conversation, and to give one concrete example per answer. Tell them not to soften it; the softening is the measurement error.
2. What do I say I want, and what do my choices suggest I want?
3. Where am I least accurate about myself?
4. What do I do that I would deny doing?
5. What have I changed in the last two years that I have not acknowledged?
Then answer the same five about yourself, before reading theirs. The gap between the two sets is the data. Do not argue with it; write down where it is largest and check it against your record for the same month.
Two cautions. Informants have their own biases, including politeness and the version of you they need. And a single informant is a single study; two who disagree with each other are more informative than two who agree.
