Presentation. What does this have to do with web development?

Developers often have to deal with competing requests for changes and additions to websites. These are not always constructive or well thought out.

In a work environment you may need to deal with managers and/or clients who expect you to do what they say.

Critical thinking helps you to behave professionally and question poor choices.

Example: Lead introduces the client request “I would like the title of my website to flash”

Lead pastes the proposition into Slack and students add emojis to show which one they think is the strongest. #1 makes a strong statement, but provides no evidence

#2 No evidence, based on emotion

#3 Quotes a source and makes an argument that will affect all sighted users of the website
