The brain has a tendency to fill things in, so that is probably why.

<p>The question is about <a href="https://www.facebook.com/DeceptionExpert/videos/vb.442668942581631/581023625412828/?type=2&amp;theater" rel="nofollow">this</a> video. </p>

<p><strong>Summary of the Video:</strong> (can skip if you watched it)</p>

<p>The only audio is "elevator music." There is a man who communicates only with written orange signs. He asks the viewers to quickly perform some easy arithmetic calculations, and he shows the answer to each one after a few seconds:</p>

<p>$5+3 \ \ = 8$</p>

<p>$9+2 \  \ =11$</p>

<p>$10-6=4$</p>

<p>Then, he asks the viewer to quickly pick a number between $5$ and $12$. At this point, I suddenly felt a sense of urgency, and rapidly picked $7$; it was the only number I could think of in that second. Of course at the end of the video, the man guessed that the subject picked $7$. </p>

<p><strong>Question:</strong></p>

<p>How does this video influence the viewer to pick $7$? More generally, what techniques do these types of videos employ to try to manipulate the subject into chosing a certain outcome?</p>

<hr>

<p>I tried to look for certain patterns in the calculations and I found a diagonal symmetry, but I'm not sure if it's relevant: </p>

<p>$\color {red}{\text{odd}}  \ \ + \color {red}{\text{odd}}$</p>

<p>$\color {red}{\text{odd}}  \  \ +  \color {blue}{\text{even}}$</p>

<p>$\color {blue}{\text{even}} \  +    \color {blue}{\text{even}}$</p>

<p>I've also noticed that the average of the $3$ results is $\dfrac {8+11+4}{3} = 7. \overline {6}$</p>

Before explaining a phenomenon, we have to describe it accurately. Can you provide any evidence that this person really can influence your choice? I couldn't do it myself because I read your summary first, but I'd be surprised if the video made any difference. It may also be worth noting that people do not behave randomly when choosing numbers and 7 is a popular one anyway (it's many people's lucky number, for example).

The question is about [this](https://www.facebook.com/DeceptionExpert/videos/vb.442668942581631/581023625412828/?type=2&theater) video.

**Summary of the Video:** (can skip if you watched it)

The only audio is "elevator music." There is a man who communicates only with written orange signs. He asks the viewers to quickly perform some easy arithmetic calculations, and he shows the answer to each one after a few seconds:

$5+3 \ \ = 8$

$9+2 \ \ =11$

$10-6=4$

Then, he asks the viewer to quickly pick a number between $5$ and $12$. At this point, I suddenly felt a sense of urgency, and rapidly picked $7$; it was the only number I could think of in that second. Of course at the end of the video, the man guessed that the subject picked $7$.

**Question:**

How does this video influence the viewer to pick $7$? More generally, what techniques do these types of videos employ to try to manipulate the subject into chosing a certain outcome?

[Priming](https://en.wikipedia.org/wiki/Priming_(psychology)) is a phenomenon where an exposure to a stimulus affect/influences response to another stimulus. It is however, a broad definition which may or may not fully explains what actually happened in the video.

For what's it worth, I notice that number 7 was the only number (between 0-9) that didn't appear at all in any of the arithmetic calculations, answers or questions. But I can't say that I understand how this could influence subject's choice.
