Q: How to convince colleagues about my point of view in a meeting?
A: You may need to explain your point a few different ways, if others don’t grasp what you said at first. The general rule of presenting (1. tell them what you’re going to say; 2. tell them; 3. tell them what you’ve said) also applies.
There are many oratorical tricks that will help get your point across: repetition, alliteration, the use of “we” and “us”, and of course the rule of three.
There are also plenty of rhetorical devices you can use – probably the most useful are analogy, thought experiments, wit or humour, inference, and reduction to absurdity. Note that these need practice.
However, if you overuse certain tricks or devices, people may spot this and discount the point you’re making.
