The Science of Persuasion:
Using Persuasion Principles & Techniques
Whether we realize it or not, we love shortcuts to thinking. When we buy an item, we don’t always take the time to research the product or read the latest consumer guide’s ratings on the product. Instead, we often rely on the salesperson’s advice, we might just buy the most popular brand, or we might bring a friend along for his opinion.
Shortcuts to thinking
If we thoroughly considered every single decision, we would constantly be overwhelmed and we’d never get anything done.
There are two paths to persuasion: the conscious and the subconscious.
Both paths can persuade others to your way of thinking, but each path uses a very different means of processing information.
Two Paths of Persuasion: The Conscious & the
Subconscious
In the conscious path, both you and your audience make an active or conscious attempt to understand, define, and process an argument.
The conscious path
A person who is interested in your persuasive attempts will be highly motivated to listen.
As such, she will also be able to consciously evaluate your message by carefully weighing the pros and cons of the evidence you present.
The conscious path
In the subconscious path, the listener spends little or no time processing the information.
This approach results in those automatic triggers.
Your mind reaches a decision without doing any logical processing.
The subconscious path
These subconscious decisions are largely driven by instinct and emotion.
They are not really involved in the subject. Here, the key is knowing when to use which method.
The subconscious path
Elaboration Likelihood Model
ELM’s two “routes” to persuasion Depends on the level of elaboration
Central route: Focus on quality of message Peripheral route: Focus on superficial “cues”
Low Elaboration
High Elaboration
Peripheral Route
Central Route
Central route Involves conscious processingCareful and thoughtful consideration
Peripheral route Involves automatic processing Influenced by some simple cues
Two Routes to Persuasion
Argument Quality In addition to what is said previously,
the cause of the elaboration also depends on the quality/strength of arguments.
Elaborated Arguments: Strong Weak
Central Route
Elaboration Likelihood Model
We may be persuaded by arguments or by peripheral cues So, does elaboration matter?
Elaboration Likelihood Model
Persuasion via the central route leads to stronger attitudes
Attitude Strength
Attitude strength Stability over time Resistance to persuasion attempts Attitude is more likely to predict
behavior
Elaboration Likelihood Model
So, is the central route better? Not always!
Central route Takes time and energy Doesn’t necessarily lead to better
decisions

Not all kinds of persuasion are created equal ELM: central vs. peripheral route
Persuasion is not inherently bad Such as health campaigns, environmental
campaigns You can resist persuasion Attitudes are very important –
Especially when they predict behavior!
