Critikid’s Story
My name is Stephanie Simoes. I started Critikid because I noticed a shortage of online critical thinking resources for children. I had been teaching children about logical fallacies and cognitive biases for a while, so I knew that not only could they understand those topics, but they loved learning about them!
I am funding this project through my savings, so a current priority is keeping costs down. Fortunately, my husband is a web developer and designer, so he takes care of the technical work. I'm covering living expenses by teaching, so all money made from Critikid's sales will go towards funding more content. I don’t have a marketing budget at this time, so if you want to support this project, it would help a lot if you spread the word!
Critikid’s Mission
These days, we have access to more information than ever before but lack the ability to properly understand it. We can interact with more people than ever but have trouble communicating effectively.
Critikid's resources give kids and teens the skills they need to rationally think about and discuss controversial issues without telling them the conclusions they should draw. My goal is to help kids and teens build a critical thinking toolkit that they can use to wisely navigate a confusing world.
What is critical thinking?
Critical thinking is slow, careful thinking. It is the process of pausing to question our assumptions, check our biases, and weigh evidence before accepting a claim or making a decision. It helps us rationally analyze information, arguments, and even our own thought processes.
What are the building blocks of critical thinking?
The following skills help people of all ages to think critically:
Recognizing logical fallacies – Logical fallacies are common reasoning errors that weaken arguments. Learning to recognize them—both in other people’s words and in our own thoughts—keeps discussions productive and clear.
Information, data, and science literacy – Facts and figures can be presented in misleading ways. Knowing how to analyze data guards us against incomplete truths.
Intellectual humility – Acknowledging that we don't know everything and that we might be wrong opens the door to learning and healthy skepticism.
Emotional intelligence – Being able to understand and manage our feelings helps us think more clearly when stakes (or tempers) are high.
Why is critical thinking important?
Critical thinking helps us to:
Communicate clearly: Logical fallacies can derail conversation. When we can identify and respond to them, we can steer conversations back on track.
Make better decisions: Critical thinking helps us recognize when our biases and assumptions are impacting our decision-making. By slowing down, we can better judge risks and rewards, compare short‑ and long‑term consequences, and choose the path that will help us reach our goals.
Defend ourselves against manipulation: Advertisers, scammers, and influencers can exploit people's biases and use logical fallacies to persuade people to buy things or accept ideas. Critical thinking makes their tricks easier to spot and ignore.
Why teach kids critical thinking to kids?
Our brains love shortcuts. Left on autopilot, we tend to accept the first explanation that feels intuitively right. Slow, careful thinking is not our default—it’s a skill that takes practice, just like reading or riding a bike. That’s why kids need explicit lessons in critical thinking.
This applies to people of all ages, but starting early is best because it:
Builds good habits before bad ones set in – It’s easier to learn pause and question now than to unlearn snap-judgments later.
Turns kids' natural curiosity into competence – Kids already ask “why.” Critical thinking education shows them how to test explanations, not just collect them.
Normalizes intellectual humility – Kids should grow up knowing that not having all the answers is normal and changing your mind when you get new evidence is a strength.
At what age should kids start learning critical thinking?
Children can do activities to develop their critical thinking skills even before they can talk. A toy that lights up when a button is pressed teaches cause and effect, peek-a-boo teaches object permanence, and nesting toys help develop problem-solving skills. Once kids can talk, they can start to do simple experiments. For example, you can ask, “What do you think will happen when you mix the red and yellow paint?” The child can make a hypothesis and test it by mixing the paints.
