"Yes, I'm Suren't" helps you to understand if you are overconfident, underconfident, or a combination thereof! More than that, through successive play sessions, it can help you to calibrate your confidence levels and overcome these biases.

COGNITIVE BIASES, OVER- AND UNDERCONFIDENCE

Cognitive biases poison our mental processes. While it's true that we humans are all susceptible to these biases, it's also true that we can learn how much we are affected by them, and work to minimize their effect in our thinking.

And here's where *Yes, I'm Suren't* comes in. The app is designed to help you with two of these biases: underconfidence and overconfidence (this one, a close relative of the Dunning–Kruger effect!). It aids you in measuring and calibrating your confidence levels when you say things like "I am 90% sure of that!" or "sorry, no idea!". It's a tool for improving your metacognition.

NOT YOUR REGULAR QUIZ GAME

"Yes, I'm Suren't" may look like just a quiz game on the surface, but it goes beyond that. For question you need to provide not only the answer, but you also need to assess how sure you are about it. It doesn't matter if you get the answers right or wrong. What really matters is that your confidence levels match the reality!

After each play session the app will show your results, comparing your assessed certainty levels with your actual rate of correct answers. Seeing discrepancies between those is crucial to overcome under- and overconfidence.

SELF-IMPROVE, THINK RATIONALLY, MAKE BETTER FORECASTS

Everyone can benefit of thinking more clearly and more rationally. It pays off especially for those of us whose jobs or hobbies involve making decisions based on predictions or forecasts. How could you reliably estimate the likelihood of some outcome when your reasoning is obscured by clouds you cannot even notice?

TRY FOR FREE, PLAY OFFLINE, DON'T BE SPIED, NO SUBSCRIPTIONS

You can download and try "Yes, I'm Suren't" for free. The free version comes with a limited set of questions, so after a play session or two you'll see repeated questions. If you like the app, you can purchase the full question pack, with 1000+ additional questions. And yes, this is a one-time purchase, not a subscription!

This app does not collect any data about yourself. It doesn't track you. It doesn't store your answers or results anywhere. You can play it offline, in airplane mode or whatever — well, you need to be online during the act of purchasing the full question pack, but otherwise the app fully works without an Internet connection.

NO SILVER BULLET, NO MAGIC WAND

I hate that I feel like I need to add this disclaimer, but here I go: this app is not offering or promising a "magic cure" to cognitive biasses or anything.

It will not turn you into a genius. It will not make you rich, famous, or irresistibly charming. It is a simple tool (a toy, if you will) that can help you to understand one or two of your own biases and can support your journey to minimize their effects in your thinking.

Just this! Have fun and get better!
