Biological Differences Between Liberals and Conservatives

According to the largest study of its type, brain scans of individuals obtained as they engaged in different activities or even did nothing accurately indicated whether they were politically conservative or liberal.

Researchers discovered that the “signatures” in the brain revealed by the scans were just as good at predicting political ideology as the strongest predictor often employed in political science studies, a person’s parents’ ideology.

“Can we understand political behavior by looking solely at the brain? The answer is a fairly resounding ‘yes,’” said study co-author Skyler Cranmer, the Phillips and Henry Professor of Political Science at The Ohio State University.

“The results suggest that the biological and neurological roots of political behavior run much deeper than we previously thought.”

Doesn’t surprise me in the least. Although, as a piece of modern scientific research, there still isn’t any conclusion on which causes the other. Education and training vs any inherent trend.

    Awesome. This will be a great tool to help weed out those that hold, as Trudeau put it, ‘unacceptable views’. Now we just need the right combination of incarceration and therapy to correct the problem. I’m sure the Chinese could give us a leg up.

    Dear Eideard,

    I concur with you that there are biological differences between liberals and conservatives. There is plenty to explore regarding the escalating conflicts between the two major parties. Any reasonable and discerning person can conclude that the USA has been plagued by ignorance, dogma, falsity, blind faith, spiritual stagnation and epistemological impasse . . . . .

    Apart from what you have discussed in your post, even just the fallouts of the main event regarding the SCOTUS’ decisions on abortion and its striking down Roe v. Wade can have various implications and ramifications for the following:

    Reproductive freedoms…
    LGBTQ freedoms…
    Contraceptive freedoms…
    Migrants freedoms…
    The freedom of liberty (common sense gun safety, and police reform)…
    The right to vote…

    We have been witnessing so clearly the insidious nature of Trumpism, Machiavellian conservatism and inimical illiberalism perverting democracy for nefarious purposes and for justifying, obfuscating or muddying the waters of systemic sexism, racism, historical negationism, discrimination, marginalization and curtailment of civil rights. Given your position and concerns, you are hereby invited to peruse my latest post entitled “🏛️⚖️ The Facile and Labile Nature of Law: Beyond the Supreme Court and Its Ruling on Controversial Matters 🗽🗳️🔫🤰🧑‍🤝‍🧑💉“, as I am certainly very keen and curious about what you will make of my said post published at

    At the “Conclusions” section, I have mentioned an engaging presentation (dated 30 May 2016) about predicting people’s political convictions based on neuroscientific analyses of differences between liberals and conservatives in cerebral structure (with 71.6% accuracy) and brain activity (with 82.6% accuracy) as opposed to parental influence (with 69.5% accuracy).

    I welcome your input and am curious to know what you make of my said post as well as your perspectives on those matters discussed in my post. I look forward to savouring your feedback there!

    Wishing you a wonderfully productive August doing or enjoying whatever that satisfies you the most!

    Yours sincerely,
