Building Credibility
Using Evidence
Reasoning
Appealing to Emotions
Introduction
“The day when you could yell and scream and
beat people into good performance is over.
Today you have to appeal to them by helping
them see how they can get from here to there,
by establishing some credibility, and by giving
them some reason and help to get there. Do all
those things, and they’ll knock down doors.”
1998)

(Johnson,
Introduction
What are the oral presentation objectives ?
Why do you want to persuade your
audience?


I. Building Credibility (Ethos)

Credibility
is
how
people
consider a
speaker
as
being
qualified to speak on a
given topic.
I. Building Credibility (Ethos)

(I. Building Credibility (Ethos
How to enhance it
II. Using evidence

Evidence:
Support
your speech
with
documents
and
materials to prove or
disprove something
II. Using evidence
III. Reasoning

Reasoning
:
drawing
a
conclusion on the
basis of evidence
III. Reasoning
III. Reasoning From specific instances
Guidelines
1.Avoid hasty generalization
2.Be careful with wording
3.Use statistics
III. Reasoning From principle
?What dose it mean
III. Reasoning Causal
Seeks to establish the relationship between
causes and effects
Errors to avoid:
I. The fallacy of false cause
II. Assuming that events have only one cause
False cause:
An error in causal reasoning in which a
speaker mistakenly assumes that because
one event follows another, the first event is
the cause of another
III. Reasoning Analogical
Analogical reasoning:
Reasoning in which a speaker compares two
similar cases and infers that what is true for
the first is also true for the other
 Invalid analogy:
An analogy in which the two cases been
compared are not essentially alike

Fallacies
Fallacy is: an error in reasoning
There are 5 types

Bandwago
n
Slippery
Slope

• Assumes that because something is popular, it’s therefore good,
correct or desirable (Peer Pressure)
• Assumes that taking a first step will lead to subsequent steps that
cannot be prevented (The Camel's Nose)
( Emotional Appeals (Pathos







Some of these emotions are:
Fear: economic hardship, illness
Compassion: for the physically disabled,
neglected animals
Pride: in country, in family
Anger: at terrorists, at landlords
Guilt: about not helping people less fortunate than
ourselves
Reverence: for an admired person
( Emotional Appeals (Pathos







How to generate them?
Use emotional words : (the promise of America
sparkles in the eyes of every child)
Develop vivid examples : (Nathan was only five years
old when the fever struck him)
Speak with sincerity and conviction : (not only words,
but also tone of voice, rate of speech, gestures, facial
expressions)
Emotional appeal should be guided by a firm ethical
rudder in seeking immediate action and should never
be substituted by evidence and reasoning
