How we change what others think, feel, believe and do
Personal pronouns may be the subject or object of a sentence. They are a replacement for a name of person or thing or group.
An important element for changing minds is that they signal Identity, both individually (note the capital letter 'I') and collectively. The can also signal identity by contrast of separation, talking about things and other people.
Possessive pronouns shows ownership for each of pronouns. They are significant for changing minds in that much persuasion is about possession -- if not of physical items (as in sales) then of ideas, beliefs and values (as in religious proselytizing).
For the sake of completeness and clarity, possessive adjectives are also shown here, as these are easily confused with possessive pronouns.
Reflexive pronouns talk reflexively about the person, thing or group, thus turning it in on itself.
In changing minds, there is a confirming aspect to reflexive pronouns, as 'my-self' effectively repeats the identity reference.
Interrogative pronouns ask questions of people and things. You cannot ask 'who' of yourself or another person.
In changing minds, asking 'who' places the person in the objective third person. Making something objective reduced emotion, although interrogative questions can seem like interrogation and be rather emotive.
Interrogative pronouns include who, whom, which, what.
Demonstrative pronouns, including this, that, these, those, show a contrast between things that are cognitively close or distant.
