In Gulenko's book there's the following excerpt:
"1. Left irrationals (Marshall, Craftsman, Lyrist, Advisor) are the moststress-resistant types. Their advantage is that they are good at solvingproblems under extreme conditions. A sudden change in the situationmobilizes them, giving them new strength. The ability to act effectively instress imposes on their temperamental characteristics an additionalcharacteristic: elasticity.
2. Right irrationals (Politician, Mediator, Searcher, Critic) form a groupof stress-training sociotypes. It is characterized by a gradual adaptation toextreme conditions. Each of the four goes through their “school ofsurvival,” increasing each time the
degree of resistance. An additional component to their typicaltemperaments is viscosity.
3. Left rationals (Entrepreneur, Enthusiast, Analyst, Guardian) belong tothe group of stress-braking sociotypes. They are able to withstand stressfor quite a long time, but with each new wave of stress, their forces are depleted, and they change the tactics of confrontation to self-elimination,hiding inside their inner turmoil. They seem to build a framework withinthem. An additional component of their rational temperaments iscrystallinity.
4. Right rationals (Administrator, Mentor, Inspector, Humanist) are partof a group of stress-nonresistant sociotypes. They suffer the worst of allstress, especially of a sudden nature. Despite external stoicism, theyalways have a poorly protected, vulnerable point and at the same time —the need to have strong support under their feet, a sudden blow to whichdeprives them of resistance. Drawing into a stressful strip threatens themwith serious doubts, leading to an internal breakdown (“the colloxen onclay feet”). In their rational temperaments, there is invariably such acomponent as monolithic character."
This suggests that right irrationals are less vulnerable to stress than the left rationals however most articles i've read before Gulenko's book suggest the opposite:

Who is right? And which types appear more vulnerable to stress in your day to day life, I myself strongly suspect that irrationality has more to do with managing stress than being process or result.
