Pavlov stipulated two types : Strong and Weak.
One socionist (don't remember his name) said Weak types were IP types, and Strong types all others.
More accurately :
- EJ is Strong, Balanced, and Mobile.
- IJ is Strong, Balanced, and Inert.
- EP is Strong and Non-balanced.
- IP is Weak.
But how are Strong types strong, and Weak types weak ? Is there a difference in conditioning practice between Strong and Weak types ?
