Invalidation Bias
A bias where one systematically invalidates sources of opposing information—attacking credibility, questioning motives, dismissing expertise—rather than engaging the information itself. Invalidation Bias doesn't need to refute claims; it just needs to discredit the source. If the source can't be trusted, the information doesn't need to be considered.
"He never addressed her arguments—just attacked her credentials, her funding, her personal life. Invalidation Bias: when you can't beat the message, discredit the messenger. The information remains unaddressed, but that's the point. Invalidate first, think never."

Objection Bias
A reflexive tendency to object to any claim that conflicts with one's existing beliefs. Objection Bias operates at the level of instinct: before evaluation, before consideration, the mind says "no." It's the cognitive equivalent of a knee-jerk reaction—objection first, reasoning later (if ever). The bias protects existing beliefs by making objection the default response to challenge.
"She hadn't even finished her sentence before he objected. Didn't matter what she said; if it challenged him, the answer was no. Objection Bias: the mind that says no before it knows what it's saying no to. Not reasoning, just reflex."

Contestation Bias
A bias where one automatically contests, challenges, or disputes any information that doesn't align with preexisting views. Contestation Bias doesn't just ignore opposing evidence; it actively fights it, demanding impossible standards, shifting goalposts, and finding reasons to reject. It's the bias of perpetual opposition—the mind that says "no" before hearing the question.
"Every study she cited, he contested. Methodology, sample size, funding source—always a reason to reject. Contestation Bias isn't skepticism; it's automatic opposition. Not "show me evidence," but "your evidence is never enough." The contest is the point; truth is secondary."

Denial Bias
A cognitive bias where one systematically denies, rejects, or dismisses information that contradicts existing beliefs, regardless of evidence. While confirmation bias seeks confirming information, Denial Bias actively refuses contradictory information—not just ignoring it, but fighting it, explaining it away, or attacking its source. It's the bias of the closed mind, the immune system of belief rejecting foreign evidence. Denial Bias explains why facts don't change minds: the mind isn't processing facts; it's denying them.
"He didn't just ignore the evidence; he attacked it, questioned its sources, invented conspiracies to explain it away. That's Denial Bias—not just failing to seek confirming information, but actively rejecting anything that threatens what he already believes. Facts don't work on denial; denial works on facts."

Left-wing Human Sciences
A broad framework applying left-wing values to all disciplines studying human life—history, psychology, sociology, anthropology, and more. Left-wing Human Sciences examine how human experience is shaped by power, inequality, and social structure, and how knowledge can serve liberation. They draw on Marxist, feminist, anti-racist, and other critical traditions to analyze both human reality and the disciplines that study it. Left-wing Human Sciences are self-aware about their own political commitments, rigorous in their analysis, and committed to human flourishing.
"Psychology can pathologize resistance or it can understand it. History can celebrate power or it can tell stories from below. Left-wing human sciences choose—to study with the oppressed, to analyze with liberation in mind, to produce knowledge that serves freedom. Not propaganda, but scholarship that knows it's always political and chooses its politics wisely."

Left-wing Social Sciences
An umbrella term for social science approaches informed by left-wing politics—analyzing society through lenses of class, race, gender, and power, with commitment to equality and justice. Left-wing Social Sciences include left sociology, left economics, left political science, and others—all examining how social structures produce inequality and how change might be possible. They don't pretend to be value-neutral; they acknowledge that all social science has political implications, and they choose sides with the oppressed. Left-wing Social Sciences are both rigorous and committed—understanding the world to change it.
"Mainstream economics assumes markets are efficient. Left-wing economics asks: efficient for whom? At what cost? Who's excluded? Left-wing social sciences don't pretend neutrality; they take sides—with evidence, with analysis, with justice. Not ideology pretending to be science, but science that knows it's always political and chooses which politics to serve."

Leftist Anthropology
A leftist approach to anthropology—studying human diversity with attention to power, inequality, and resistance, and with commitment to human liberation. Leftist Anthropology asks: How do economic systems shape cultures? How do people resist domination? What can we learn from societies that organize differently? How can anthropology serve struggles for justice rather than colonialism or exploitation? Drawing on Marxist, feminist, and anti-colonial traditions, Leftist Anthropology studies humans with solidarity, not just curiosity.
"They studied a society and called them 'primitive.' Leftist Anthropology asks: primitive by whose standards? What about their economy, their resistance, their wisdom? Anthropology can exoticize or it can learn. Leftist anthropology learns—from everyone, especially those fighting domination. Not just studying others, but standing with them."
