I’m a political scientist, and I found that Americans were far less likely to publicly voice their opinions than even during the height of the McCarthy-era Red Scare.

According to a 2022 book written by political scientists Taylor Carlson and Jaime E. Settle, fears about speaking out are grounded in concerns about social sanctions for expressing unwelcome views.

And this withholding of views extends across a broad range of social circumstances. In 2022, for instance, I conducted a survey of a representative sample of about 1,500 residents of the U.S. I found that while 45% of the respondents were worried about expressing their views to members of their immediate family, this percentage ballooned to 62% when it came to speaking out publicly in one’s community. Nearly half of those surveyed said they felt less free to speak their minds than they used to.

About three to four times more Americans said they did not feel free to express themselves, compared with the number of those who said so during the McCarthy era.

No better example of this can be found than in the absence of debate in the contemporary U.S. about the treatment of the Palestinians by the Israelis, whatever outcome such vigorous discussion might produce. Fearful of consequences, many people are withholding their views on Israel – whether Israel has committed war crimes, for instance, or whether Israeli members of government should be sanctioned – because they fear being branded as antisemitic.

Many Americans are also biting their tongues when it comes to DEI, affirmative action and even whether political tolerance is essential for democracy.
