Everything You Know Is Wrong

My adolescence was profoundly shaped by hours alone in my room listening to comedy albums, memorizing them—George Carlin and Richard Prior. My aunts and uncle also introduced me to the comedy group Firesign Theatre, whose Everything You Know Is Wrong may serve as the ideal message for educators.

Recently, Jessica McCrory Calarco reported in Why rich kids are so good at the marshmallow test:

The failed replication of the marshmallow test does more than just debunk the earlier notion; it suggests other possible explanations for why poorer kids would be less motivated to wait for that second marshmallow. For them, daily life holds fewer guarantees: There might be food in the pantry today, but there might not be tomorrow, so there is a risk that comes with waiting. And even if their parents promise to buy more of a certain food, sometimes that promise gets broken out of financial necessity.

And from Science DailyStudy finds popular ‘growth mindset’ educational interventions aren’t very effective:

A new study co-authored by researchers at Michigan State University and Case Western Reserve University found that “growth mindset interventions,” or programs that teach students they can improve their intelligence with effort — and therefore improve grades and test scores — don’t work for students in most circumstances.

Also consider Will Thalheimer’s People remember 10%, 20%…Oh Really?:

People do NOT remember 10% of what they read, 20% of what they see, 30% of what they hear, etc. That information, and similar pronouncements are fraudulent. Moreover, general statements on the effectiveness of learning methods are not credible—learning results depend on too many variables to enable such precision. Unfortunately, this bogus information has been floating around our field for decades, crafted by many different authors and presented in many different configurations, including bastardizations of Dale’s Cone. The rest of this article offers more detail.

Yet another example is the zombie that will not die, the “word gap”—debunked again in Reexamining the Verbal Environments of Children From Different Socioeconomic Backgrounds, by Douglas E. Sperry, Linda L. Sperry, and Peggy J. Miller:


Amid growing controversy about the oft‐cited “30‐million‐word gap,” this investigation uses language data from five American communities across the socioeconomic spectrum to test, for the first time, Hart and Risley’s (1995) claim that poor children hear 30 million fewer words than their middle‐class counterparts during the early years of life. The five studies combined ethnographic fieldwork with longitudinal home observations of 42 children (18–48 months) interacting with family members in everyday life contexts. Results do not support Hart and Risley’s claim, reveal substantial variation in vocabulary environments within each socioeconomic stratum, and suggest that definitions of verbal environments that exclude multiple caregivers and bystander talk disproportionately underestimate the number of words to which low‐income children are exposed.

But let’s not forget higher education: Arthur G. Jago asks Can It Really Be True That Half of Academic Papers Are Never Read?, discovering:

Frustrated, I ended my search for the bibliographic equivalent of “patient zero.” The original source of the fantastical claim that the average academic article has “about 10 readers” may never be known for sure.

So what’s going on as educators and scholars are confronting that everything you know is wrong? I think have some ideas, outlined below:

  • Teachers, notably K-12 educators, are practical to a fault. Teachers want what works in the day-to-day tasks of teaching students (a more than reasonable expectation) but often feel educational philosophy and theory are a waste of their very limited time (again, this time-crunch is a rational response to unreasonable working conditions for most K-12 teachers). The problem with a what works mentality absent a philosophical and theoretical lens is that the wrong basis for determining “works” often guides our practices. As a brief example, many classroom strategies can seem to “work” when students are quiet and complete the assignment, but those may be achieving compliance and not the larger (assumed) academic goal—actually working counter to those goals in fact.
  • Too often teaching can become almost entirely focused on implementing a program (think reading programs or International Baccalaureate) or fulfilling an ideology (think grit and growth mindset) at the exclusion of the instructional goals those programs or ideologies are supposed to achieve. This happens, I think, in part because of the concern for practicality noted above as that is impacted by the historical focus in education on efficiency—what is the easiest and most manageable ways to make this think called teaching and learning happen?
  • Programs and ideologies, however, are often flawed from the beginning because the research they are grounded in is distorted and oversimplified by publishers and advocates. Compounding these oversimplifications and distortions are the media, also complicit in framing complex research in ways that mislead the public and educators. Too often as well, the misconceptions are compelling and robust because they match social norms (stereotypes, biases, cultural myths) more so than reflecting the nuances and limitations of the research. As I have detailed, for example, academic and economic success and failure are far less about any person having or not grit or a growth mindset and more about systemic privilege and disadvantage.
  • Classrooms, teachers, and students are more likely to reflect all aspects of communities and society than to work as change agents for any person or community/society. Teaching and learning, then, become about normalizing, and thus, regardless of what research shows (especially when much of that research is counter to norms), it becomes a tool for the normalizing. One study on the “word gap” by Hart and Risley has become an unexamined fact, not because it is quality research (it isn’t) but because it reinforces cultural myths about social class, deficit ideologies that praise the wealthy and demonize the poor.
  • Teaching and learning are incredibly complex and the consequences of teaching—learning—are rarely easily linked to a single cause (a teacher, a class, a program or ideology) and may not manifest themselves until years later.
  • Too many researchers, consultants, administrators, and teachers become personally, professionally, and financially invested in programs and ideologies—at the expense of everything else, notably students.
  • From K-12 to higher education, teaching and learning are mostly corporatized; in that environment, research, nuance, and uncertainly have no real chance. K-12 schools and universities/colleges are incentivized for many outcomes other than teaching and learning.
  • Educators, the public, and the media embrace contradictory ideas about “scientific” and “research”—simultaneously idealizing and trivializing.

In the big picture, I think the problem of research and evidence as that becomes teaching practices can be better understood through the lens of what is wrong with Teach For America—an organization that very likely has good intentions and invites as well as promotes missionary zeal.

Good intentions are never enough, and missionary zeal is guaranteed to distort everything it touches.

It may well be true that everything you know is wrong, but that doesn’t mean it must stay that way. Good intentions and missionary zeal must be replaced by greater philosophical awareness and the sort of skepticism a critical lens provides.

This is not about fatalism—giving up on research—but about finding a better way forward, one that rejects programs and blanket ideologies and keeps our focus on students and learning along with the promises of formal schooling as a path to equity and justice, not test scores and compliant students.
