Social Intelligence is the ability to toggle and jockey tacit turntables called personalities like a Serato & MP3.
However according to Wikipedia as Social intelligence is the capacity to know oneself and to know others. Social intelligence develops from experience with people and learning from success and failures in social settings. It is more commonly referred to as A. "tact", B. "common sense", or C. "street smarts".
An important note is that A (aka the glue), B & C can be intermittently confused and even more so misunderstood but without the "know how"...dexterity or skill set it is difficult to execute meaningful use.
