Narrow thinking

See anchoring, framing, selective
exposure, tunnel vision,
heuristics, reductionism, focalization,

The brain might be stuck in one direction.

Why not train it to rotate like a ship radar?


Narrow thinking / narrow mindedness (or
selective thinking / selection bias
) is focusing
the mind on only one element of an
issue and neglecting (or even denying) others.

See in this glossary the "selectivity bias" table.

An omnipresent bias

About every brain carries a mild or acute form of the virus.

Maybe that is why brains have problems to understand one another
and how fights start in the Dodge City saloon.

This overly selective mental bias is very common... and a source of
disastrous decisions, in business and finance (and in other activities).

Narrow thinking results from

either cognitive defects (in attention, memory, logic)

and/or emotional influences (attractions, aversions).

Narrow mindedness can affect even the highest intellectual authorities.
Here a factor might be vested academic interests. They make them deny that
they have to broaden their attitude, .

It takes many forms of narrow / reductive thinking, such as :

Specific ones More general ones

Those with an important role in
economic / financial behaviors

Anchoring, framing, selective exposure,
tunnel vision, availability heuristics (and
other heuristics), reductionism, numeracy
bias, focalization, denial of realities,
cognitive dissonance...

Every one has its article in this glossary

Other forms, less related to
finance / economics,
less developed in this article,
but quite widespread, with
deep impacts in individual
and social life

Let us cite the extreme ones:

Rigid principles, dogmas,
tenets, fundamentalism,
fanaticism, purism....

It might even be a paradigm

Let us call it extreme narrow logic.

The binary / formal / Aristotelian logic is often praised as the
epitome of rationality.

Its flaw is that it sees things always as either true or false, good or bad,
excluding the
possibility of intermediate shades or more
complex approaches

Such an  "narrow logic":

* Is useful in reasonings when things are clear-cut (*).

* But, as any dogma, it sometimes contributes to narrow
- with extreme consequences - when they
   meet evolving,
many-sided and uncertain situations,
    as the "fuzzy logic"
article explains.

(*) To be half pregnant is a bit hard to understand, but even so pregnancy can be
      seen to follow several phases.
