You did not underline any portion, but let me help you with this consideration. We can revise and make it more clear this part: “easily fooled”. Let’s make it more formal for a thesis.
We know that a strong statement is a key element when writing a thesis.

Our new thesis statement is more formal, more academic and it is specific.
