Does having multiple receiver antennas close together cause IMD?

[Izen Ears]

I feel like I know this answer already, but I had a conversation recently with an RF dude and now I'm looking for the definitive facts. This dude told me you'll get IMD if your receiver antennas are too close together. That instantly rang false, and I figured he misspoke and meant to say transmitter antennas. But nope, he meant receiver antennas. 
 

That didn't make sense but he was adamant. I looked up a Shure article that I think shows I am correct. Am I?

My understanding is that Rx Antennae do intermodulate with each other, but I've never been able to understand the science behind it.  So, I understand your skepticism.  Maybe it's a popular myth?  I'd love to hear someone with knowledge explain why or why not.

More accurately, multiple receiving antennas together will affect each other. It won’t be intermodulation but they can get detuned and their directional patterns will change. Note that a Yagi unidirectional antenna is a dipole with additional elements placed closely for example, where “closely” means at a distance less than a wavelength.

Not only that, it's a discussion I started!  Thanks for digging it up.  I needed the reminder.

Solved! Thanks for the link and a big thanks to abuck50 for posting this Lectro article that says this, which explains:

 

"... antennas are receiving and re-broadcasting at the same time. As that radio wave moves up and down the antenna it creates a current. And as that current moves up and down your antenna it creates an EM wave (which come to think about it is how a transformer works). So you likely end up with neighboring antennas that are broadcasting into each other. Likewise as the front end of your receiver converts those currents into something it can demodulate it leaks a bit of signal backwards back out into your antenna where it is broadcast out and into your other antennas in the farm which will show up as an increase in noise floor."
