Hey, do any other ISTPs find this description true lol
Source: ISTp uncoveredThe most obvious thing that could give ISTps away is probably their obsession with pets. Sometimes it could reach ridiculous dimensions, turning ISTp's place into a zoo. This obsession is very closely connected with ISTp's hidden agenda. Since ISTps have unconscious need to be able to show their affection towards another, who could be a better suitable candidate for this than a pet, or better a dozen of them. People can reject your love and your good intentions, pets will never.
(Caution: MBTI ISTP do not necessarily translate to Socionics ISTp, but rather ISTx)
