Decoding Trust- A Mathematical Approach

naïve or experienced, young or old, we all in our lifetime have this one
5-letter word making us call out the usual 4-letter word that starts with
letter “F”.

why is ‘Trust’ as a word used more and understood less? Is it one of the
necessities of leading a meaningful life? Is it too basic a word to break it
further? What is it after all?

attempt at approaching this ‘Trust’ thing started 2 hour ago when idling on bed
to recover from a bad cold, I could not think of anything more meaningful. So
interpret what I say below at your discretion. May be for me it’s a time pass…

= TRU + US + ST

simple terms:

truthfulness; US= You and I ; ST = Statement (i.e. relating to communication,


a. Unlike
‘Belief’ which is an individual attribute, ‘Trust’ is a dependent attribute impacting
the intensity of TRUST

b. Truthfulness
is a constant which is governed by habits, desires and passion. All of these
attributes develop over the years and are a function of family background,
culture, education, behaviors and past experience relating to ‘Trust’ as a

c. The
equality while presented as a simple function is not so. It’s a far more complex
due to introduction of lag variable of ‘TRUST’. In other words, TRUST equation
is a time-series function and hence past experiences impact the future
In econometric (time lag variable)- Trust(t) is impacted by Trust(t-1….)

d. ‘ST’ Statement here is assumed to be a function of ‘Art of Communication’ X (Tone + Language).

e. The
equation differentiates between ‘Tone’ and ‘Language’ akin to the 4-letter work
starting from letter ‘f’…explained by Osho as Verb, Noun, adjective,
intransitive verb, anger, surprise etc. I hope my readers have heard that
famous preaching of Osho. Link to the video is here –
I was done with stating the Trust Equation, I ‘googled’ to avoid re-inventing
the wheel and to my surprise Google had an answer:
Credibility +
Reliability + Intimacy    DIVIDED BY    Self-orientation
the equation defined by me above is not very different from equation above. However,
the relation between the variables in above equation is better expressed as
given below:
Credibility + Trust
(from past) + {(Reliability X Intimacy)    DIVIDED BY    Self-orientation}
can have only two values -1 or +1 . I am deliberately avoiding the infinity
notion here since we all have a defined life.

simplify the interaction amongst the variables we assume that all the variables
can either have a minus 1 or a plus 1.

possible solutions to the equation are:

Please read + 1 as YES and -1 as NO.

the above illustration explains that we can either HAVE Trust or NOT HAVE
Trust. No other possibility exists.
