Why Credentials Matter: Don’t Let Social Media Influence Silence Your Voice

Introduction

In today’s digital world, social media has given everyone a platform to communicate, educate, influence, and express opinions. However, having thousands of followers does not automatically mean that a person has education, professional training, or expertise in the subject being discussed. This is one reason credentials remain important.

Degrees, professional licenses, certifications, and specialty credentials represent more than letters placed after a person’s name. They communicate education, training, competency development, and commitment to a profession. Displaying legitimate credentials on social media should therefore not automatically be viewed as boasting. When credentials are accurate and relevant, they can provide transparency about who is speaking and what qualifications support that person’s professional perspective.

This has become particularly important because social media increasingly influences how people obtain information. In 2026, the Pew Research Center reported that approximately 40% of U.S. adults obtain health and wellness information from social media influencers or podcasts. Pew also found that many health and wellness influencers identify their professions or credentials in their profiles specifically as a way of signaling their authority to discuss particular subjects.

Why Displaying Credentials Can Be Valuable

1. Credentials help establish professional credibility.

When people encounter information online, they often have limited information about the person providing it. Professional credentials provide one way for readers to evaluate whether the individual has relevant preparation in the subject.

Research supports this. Kuutila and colleagues studied 844 adults who completed 8,380 evaluations of health-related social media posts. Source expertise was one of the strongest factors affecting how credible participants perceived the information to be.

This does not mean that a credentialed person is always correct. Rather, credentials provide important information about the source that readers can consider along with the quality of the evidence being presented.

2. Credentials can communicate skills to employers and professional networks.

There is also evidence that publicly sharing credentials can have career value. A large randomized study by Athey and Palikot involving more than 800,000 learners examined the effect of encouraging people to share educational certificates on professional networking platforms. Participants encouraged to share their credentials were more likely to report new employment, including an approximately 8% increase in jobs related to their certificates. The researchers concluded that credential sharing can function as a form of skill signaling in the labor market.

In other words, if you invested time and effort developing a professional competency, making that qualification visible can help employers and colleagues understand what knowledge and skills you bring.

3. Credentials contribute to professional identity.

Professional identity is built through education, experience, professional responsibilities, values, and qualifications. A large scoping review of professional identity research across health professions identified learning and qualifications as one of the major components contributing to professional identity.

Research also suggests that professional identity now extends into the digital environment. Ruan and colleagues described social media as a space where healthcare professionals develop and communicate a “digital self,” meaning that how professionals represent themselves online has increasingly become part of their professional identity.

Credentials Are Not About Being Better Than Others

Displaying credentials should never mean, “I am better than you.”

Instead, it can mean:

This is what I studied.
This is what I trained for.
This is an area in which I developed professional competence.
This is the perspective from which I am speaking.

There is also an important responsibility attached to credentials. Credentials should be truthful, verifiable, current when required, and relevant to the subject being discussed. Professionals should still support their statements with reliable evidence. A degree, license, or certification does not make every opinion automatically correct.

Don’t Let Social Media Influence Silence Your Professional Voice

Social media popularity and professional expertise are not the same thing. Someone may have a larger audience, but audience size should not determine whose knowledge deserves to be heard.

Professionals should be able to respectfully share their education, experience, credentials, and evidence-based perspectives without feeling that they must remain silent because another person has more followers or greater social-media influence.

Credentials do not replace evidence—but they provide context for expertise.

Be proud of what you have worked for. Continue learning. Continue earning meaningful credentials. Continue checking the evidence.

Credentials displayed on social media should not automatically be interpreted as showing off. Particularly in healthcare, identifying one’s legitimate degree, license, certification, or specialty credential provides transparency about the education and professional preparation behind the information being shared. Research indicates that source expertise influences how people evaluate the credibility of health information online (Kuutila et al., 2024), while a recent systematic review found that credentials and professional affiliations can function as important cues of expertise in social-media environments (Simmonds et al., 2026). Credentials do not replace scientific evidence, but they help the public understand who is speaking, the professional preparation behind that voice, and the accountability associated with it.

And most importantly:

Never allow popularity to silence knowledge, education, experience, and a professional voice grounded in evidence.
