Mentioning the Pledge in your LinkedIn summary is an easy way to spread the word. Here's why you should do it, and how you might go about doing it in practice.

One of the first things that people tend to do when they want to learn about someone in a professional context is look them up on LinkedIn. As such, it could be highly impactful for you to mention your commitment to the pledge on your LinkedIn profile. Including the pledge could also make your LinkedIn summary much stronger, authentic, and convincing. More importantly, it could also encourage others to give effectively.
In short, a good LinkedIn summary:
It follows that sharing your dedication to the pledge might be a great way to communicate to others what you find important in the world. It could also show people what your personality is like beyond your work achievements and professional experience.
There can sometimes be tremendous benefits to being public with our actions. Beyond the direct value of charity, it is important to think about the knock-on effects of encouraging others to be generous. Think about it this way: pledging to donate 10% of your income throughout your working life can positively impact the lives of many others. But you can substantially increase your contribution to the world just by convincing one other person to join you in taking the pledge!
Remember, ideas cannot spread unless we share them.
We are social creatures that rely on others for cues on what we ought to do (a phenomenon known as ‘social proof’). Being an “early adopter,” argues Luke Freeman in a blogpost for Giving What We Can, can “normalise the path forward for others” to start dedicating time and money to solving the world’s most pressing problems.
The natural urge to conceal our altruism can be appealing. Telling others about our preferences, ideals, and passions can be scary (especially if it risks us coming off as boastful or pretentious). But it is sometimes needed in order to create a cascade of social change. This change will never happen — or if it does, it will happen far too slowly — if we give in silence. So let’s speak up when we can.
