Technical term for the displaying of 'bad' traits to seem more likeable What is the technical name for the public display of personal traits that are unproductive or unhealthy as an attempt to make oneself seem more likeable or relatable? (e.g procrastination)
This may not fit exactly the scenario described, but some form of strategic affect display or 'appraisal theory', these relate to social theories of (&amp; displays of) emotion, as oppose personality traits as such, but may be relevant nonetheless. 

So for example, you might want to come across as being more aggressive &amp; assertive, or alternately more compassionate &amp; caring, in any given scenario, because you feel that is the appropriate thing to do, or you may gain some advantage from that - even though you may feel otherwise indifferent about whatever it is.

Having said that, the way the question is phrased - whether something is 'productive' or 'unproductive' in a social sense, as oppose to a personal level, is open to interpretation, i.e. if it makes you more 'likeable' then it is socially productive (at least in the short term), regardless of whether it it something that is generally regarded as being a negative trait.

Hope that's relevant.
