The reason why we are so confused in life is because we just consume and never really chew information. Critikid is a fabulous website that addresses the most important skill that anyone should have, CRITICAL THINKING.

Critikid’s Story

My name is Stephanie and I'm an online science teacher and educational video creator. 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. My husband, who is a web developer, he designed and built this site. I am teaching online science classes to cover my living expenses, so all money made from 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 immensely if you spread the word.

Critikid’s Mission

Critikid’s goal is to give children the tools they need to rationally think about and discuss controversial issues, not to tell them the conclusions they should draw. Critikid’s stance is pro-logic and anti-fallacy. Besides that, I am avoiding taking stances on the side, especially about hot political topics.

Critical thinking is particularly important for children these days. They spend a huge portion of their lives on the Internet, which abounds in polarizing opinions, logical fallacies, and misinformation. This is the battlefield that the kids of today must withstand, and critical thinking is their armor. Critikid’s goal is to help them forge it.

What is critical thinking?

Critical thinking is careful thinking. It is the process of rationally analyzing information, arguments, and even our own thought processes. It lets us distinguish between logical and flawed reasoning in order to communicate clearly, even when communicating with ourselves.

Why is critical thinking important?

Firstly, critical thinking makes us better communicators. Logical fallacies frequently find their way into conversations, and when we can’t identify them, they tend to derail discussions and make them unproductive. The ability to recognize when you or your conversational partner is committing a logical fallacy can help get the conversation back on track.

Critical thinking also makes us better decision-makers. Understanding cognitive biases means understanding our minds. When we can recognize our cognitive biases, we can get a better idea of why we make the decisions we do.

People who try to sell us products or ideas know all about logical fallacies and cognitive biases, and they know how to use them to their advantage. The ability to think critically helps us to defend ourselves against manipulation.

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, a parent might ask, “What do you think will happen when I mix the red and blue paint?” The child can make a prediction and then test it by mixing the paints. In the future, I'll post critical thinking activities for kids on this site.

Critikid will offer various levels targeting different age groups. Fallacy Detectors Part 1 is aimed at children ages 8-12. The formal logic course that I am now working on will target kids 13 and up.

I’ve been teaching critical thinking to children for years now, so I know that they are not only capable of understanding it, but they love it. What kid wouldn’t find it amusing to hear about the silly mistakes that even adults can make? Moreover, childhood is the best time to strengthen the mind’s defenses and teach it to recognize its biases. It only gets harder as you get older.

Who are you?

My name is Stephanie Simoes. I’ve been a science teacher and children’s educational video creator for many years. My background is in biology and philosophy. I’m running this project with a very small team of talented freelancers.
