You are a closed book
Experimental research (by Vazire, Newton, Yudowsky, Gilovich, Medvec and Savitsky to name just a few) has shown that you overestimate how much other people know about you, how much attention they pay to you, how much they can tell about what is going on in your head.
They don’t know what is going on in your head.
But that’s okay, because neither do you.
You overestimate your own abilities in areas were you know too little. You underestimate your expertise in areas where you are an expert (Dunning-Kruger effect). You are chock-a-block with bias and false impressions and errors in perception.
That is what the Talent Profile is good at doing. It uses a powerful psychometric instrument that slips past your own cognitive blocks to figure out what really makes you tick. It gives you a solid book of instructions on how to drive your own career. It tells you how to keep yourself interested and focused at work. It tells you where the pitfalls are and points out how to get around them.
