presentation on lateral thinking and some question for better understanding on topic lateral thinking

1. Lateral thinking

2.  According to the Oxford English dictionary, Lateral Thinking is “…a way of
thinking which seeks the solution to intractable problems through
unorthodox methods, or elements which would normally be ignored by
logical thinking.
 Lateral thinking is a term coined by Edward de Bono, a Maltese
psychologist, physician, and writer
 de Bono defines Lateral Thinking as methods of thinking concerned with
changing concepts and perception.

3. 1
Lateral Thinking - Theory
The brain is not intended for creative thinking
The brains power is in forming patterns
and sticking to these patterns
SO
To become creative you need to block
normal channels and “cut across patterns
in a self-organizing information system”

4. Explaining lateral thinking
 Mind is like mud – grooves are formed where water/thoughts run. Need to
form new avenues
 “Discovery consists of looking at the same thing as everyone else and
thinking something different” Albert Szent-Gyorgyi, Nobel Prize Winner

5. Lateral Thinking
 Lateral thinking is a term coined by Edward de Bono, a Maltese
psychologist, physician, and writer
 de Bono defines Lateral Thinking as methods of thinking concerned with
changing concepts and perception.

6. Lateral Thinking Example
It took two hours for two men to dig a
hole five feet deep. How deep would
it have been if ten men had dug the
hole for two hours?
The answer appears to be 25 feet deep

7. But did you consider…?
A hole may need to be of a certain size or
shape so digging might stop early at a required
depth.
The deeper a hole is, the more effort is required
to dig it, since waste soil needs to be lifted
higher to the ground level. There is a limit to how
deep a hole can be dug by manpower without
use of ladders or hoists for soil removal, and 25
feet is beyond this limit.

8. But did you consider…?
Deeper soil layers may be harder to dig out, or we
may hit bedrock or the water table.
Are we digging in soil? Clay? Sand? Each presents
its own special considerations.
Digging in a forest becomes much easier once we
have cut through the first several feet of roots.
Each man digging needs space to use a shovel.

9. But did you consider…?
It is possible that with more people working on a
project, each person may become less efficient due
to increased opportunity for distraction, the
assumption he can slack off, more people to talk to,
etc.
More men could work in shifts to dig faster for
longer.
There are more men but are there more shovels?

10. But did you consider…?
The two hours dug by ten men may be under
different weather conditions than the two hours dug
by two men.
Rain could flood the hole to prevent digging.
Temperature conditions may freeze the men before
they finish.
Would we rather have 5 holes each 5 feet deep?

11. But did you consider…?
The two men may be an engineering crew with
digging machinery.
What if one man in each group is a manager
who will not actually dig?
The extra eight men might not be strong enough
to dig, or much stronger than the first two.

12. What is Lateral Thinking?
Lateral thinking is about reasoning that is not
immediately obvious
Ideas may not be obtainable by using only
traditional step-by-step logic.
Techniques that apply lateral thinking to problems
are characterized by the shifting of thinking patterns
away from entrenched or predictable thinking to
new or unexpected ideas.

13. What is Lateral Thinking?
 A new idea that is the result of lateral thinking is not always a helpful one
 When a good idea is discovered in this way it is usually obvious in hindsight

14. Lateral Thinking Puzzles
The Surgeon... A father and his son are
involved in a car accident, as a result of
which the father is very badly injured and
his son is rushed to hospital for emergency

operate on him". When asked why, the
surgeon replies "Because he's my son...".
How could this be the case?
Answer: The surgeon is the boy's mother...
