Build your viewpoint on facts – Anyone can have an opinion, however if you can base
your views on credible facts and information it will be a lot more solid. Think
of expressing your viewpoint like building a wall with each fact like a brick
in the wall. The more bricks you have the more sturdy the wall. Building fact
upon fact can be even more effective than scattering a bunch of information
randomly
Nonverbal communication – Your volume, your tone, eye contact, posture and
hand gestures can help make your opinion easier to follow and more persuasive
if used correctly. Try to exhibit poise.
(Poise - a dignified, self-confident
manner: composure, stability)
Avoid absolutes – Words like “never” or always” can ruin the
credibility of the point you may be trying to make. It is good to be specific
rather than make sweeping generalizations
Respect – Avoid being offensive or insulting. Usually once you
insult the person you are expressing yourself too that usually shuts down any
hope of coming to an understanding.
Focus on building up rather than only tearing
down – It can be useful to point out
some reasons why you disagree with a belief or viewpoint. However, if all that
you can bring to the table are reasons why you feel that other viewpoints are
wrong but you cannot make a positive case as to what is good about your
viewpoint then you really don’t have a leg to stand on. For example if you were
in a discussion about why you thought one sports team was better than the other
you need to be able to explain why you believe your team is good instead of
only bringing out why you think the other team stinks.
