Which principle would be least effective when working with logical individuals?

When working with logical individuals, structured arguments are especially effective because they appeal to reasoning and critical thinking. Logical individuals tend to prioritize information that is rational and well-supported. A structured argument organizes ideas in a way that is coherent and makes it easier for these individuals to follow the line of reasoning.

While evidence-based reasons, clear data, and structured arguments are foundational aspects that make a persuasive case to those who value logic, the principle of liking relies on emotional appeal and personal relationships. This principle might not resonate as strongly with logical individuals, as they may not prioritize personal feelings or connections when making decisions. They seek objectivity and factual information rather than relational dynamics, making the principle of liking the least effective in this context.
