Why is freedom of speech important in a democracy? Why is it a core principle?

Democracy’s goal is to have a plural and tolerant society. For this to happen successfully, citizens should be able to speak freely and openly about how they would like to be governed and criticize those who are in power.

This exchange of ideas and opinions isn’t just a once off on election day, rather it is an on-going two-way communication which happens throughout a government’s term.

1. It battles for the truth

To enable citizens to make meaningful decisions about how they want society to function, they need access to truthful and accurate information about a wide variety of topics. This can only happen if people feel safe vocalizing the issues affecting their communities.

Safeguarding freedom of speech encourages people to speak out, which makes it easier to tackle systemic issues from the inside. This deters people from abusing their power, which helps everyone in the long run.

2. It makes everyone more accountable

When it comes to elections, citizens are given the opportunity to hold their politicians accountable. In order to decide who to vote for, they need to understand how well a political party has performed while in power and whether or not they fulfilled their election promises.

By reporting on society’s most pressing social issues, media outlets and civil society organisations (CSOs) contribute to the public’s perception of how well the government is doing. However, this is only helpful if they are free to truthfully cover stories that are critical of the state.

3. Active participation of citizens

Elections and referendums are a good opportunity for citizens to shape the direction of society, but they only come round every couple of years.

Free speech reinforces other fundamental rights such as freedom of assembly, which citizens exercise to influence public decision-making by attending protests, demonstrations or participating in campaigns.

This allows them to protest an unpopular decision, such as the ban on abortion in Poland, or show the government they want stronger political action on an important issue. When protestors in Germany filled the streets in their hundreds of thousands protesting the war in Ukraine, this sent a strong message to the government that the people supported strong sanctions against Russia.

A more recent positive example of the effects freedom of assembly and active participation has, can be seen in Poland. The opposition was able to rally political participation through large pro-democratic protests before the election in October of 2023. Their subsequent win ousted the PiS, which was systematically dismantling principles of democracy in Poland. This shows how exercising the right to freedom of assembly and free speech helped save Poland's declining democracy.

4. Promotes equal treatment of minorities

In a democratic society everyone should be treated equally and fairly. However, minority groups who are underrepresented in government are often side-lined, and their opinions' neglected in favour of those belonging to the dominant social group.

By campaigning and speaking openly about the issues faced by their communities, marginalized people can gain widespread public support for their cause. This increases their ability to influence public agenda-setting and put an end to human rights abuses.

5. Necessary for change and innovation

We all want society to become better for everyone, but for that to happen society’s need to encourage and foster freedom of expression. Authoritarian governments who suppress criticism and withhold public interest information deny citizens the right to make informed decisions or take action about important social issues.

Concealing vital intelligence causes problems to fester and worsen. This hinders progress and makes finding a solution much harder when the issue finally comes to light.

For example in China, the doctor who attempted to warn the medical community of a deadly virus – Covid-19 – was told to "stop making false comments" and was investigated for "spreading rumours". This had the devastating effect of delaying the introduction of measures to contain Covid-19, which resulted in a global pandemic and millions of deaths.
