I am following this video
It is established that:
$\mathbf E[\tilde\Theta\hat\Theta\mid X=x] = 0.$
Using the law of iterated expectations,
$\mathbf E\bigl[\mathbf E[X|Y]\bigr] = \mathbf E[X]$
it argues that
$\mathbf E[\tilde\Theta\hat\Theta] = \mathbf E[\tilde\Theta\hat\Theta\mid X=x] = 0.$
However what I deduce from the law of iterated expectation is:
$\mathbf E[\tilde\Theta\hat\Theta] = \mathbf E\bigl[\mathbf E[\tilde\Theta\hat\Theta\mid X=x]\bigr].$
Are they saying
$\mathbf E[\tilde\Theta\hat\Theta\mid X=x] = \mathbf E\bigl[\mathbf E[\tilde\Theta\hat\Theta\mid X=x]\bigr]?$
Is this a violation of the law's definition?
The answer is:
$\mathbf E[\tilde\Theta\hat\Theta\mid X=x] = \mathbf E\bigl[\mathbf E[\tilde\Theta\hat\Theta\mid X=x]\bigr] = \mathbf E[0] = 0.$
