I guess that is why we saw in the voir dire that they asked can you do critical thinking. If somebody cannot do critical thinking, they cannot put two and two together, and all the circumstantial evidence, and put it together.
Many of us here do that with many cases, but seriously, that is what we heard in the media reports that the prosecution was asking the jurors if they were critical thinkers. Not everybody has the capability to do that even though most folks can do it easily? They know that some individuals just cannot do such it appears. The danger being though, if someone defined themselves as such, but in reality, they are not.
The prosecution recognizes such, and hopefully got rid of those during voir dire.
