Our Halloween Special: The Ghost of the Bell Curve with Rebecca Cruz

For Halloween, DiveIn brings you something truly frightening:

a statistical distribution.

Federico Waitoller talks to Rebecca Cruz, Assistant Professor at the Johns Hopkins University School of Education and coauthor, with Allison Firestone, of the new book The Ghost of the Bell Curve: Ableism in American Education and an Agenda for Change.

The book asks us to confront an uncomfortable idea: some of the assumptions that have historically shaped intelligence testing, disability classification, sorting, and educational exclusion never really disappeared.

They are still haunting us.

Rebecca and I discuss how the idea of the “average” became connected to notions of normality, how bell-curve thinking continues to shape education, and how ableism and racism become intertwined in systems of identification, discipline, and opportunity.

And then there is an interesting tension:

Rebecca critiques the legacy of the Bell Curve...

but she is also a quantitative researcher.

So can we use statistics to challenge inequities that statistics once helped create?

Can quantitative methods expose structural problems without reproducing the same assumptions about normality and difference?

We talk about critical quantitative research, QuantCrit, disproportionality, measurement, and what it would mean to build educational systems that treat human variability as expected rather than as evidence of deficiency.

Because the problem may not be the curve itself.

The problem is what happens when we turn a mathematical distribution into a story about who is normal—and who is not.

So turn off the lights.

Check under the bed.

Make sure there are no standardized tests hiding in the closet.

And Let’s DiveIn with Rebecca Cruz.
