Here a struggle caused by the Gulf of execution:

While using Booking website, I want to book a hostel and I am logged in with my account. I think that because I am logged in, I need to only click the button book, put in some the details of my arrival and confirm booking. But for some reason system asks me to type in my email and name again though I am logged in. From my perspective as a user it should not happen because it takes unnecessary extra step from me.  

Here a struggle caused by the Gulf of evaluation:

While using the Booking website I search a hostel in Singapore and it is nicely shows me how far a particular hostel is from the city center (for example 2 kilometers). Meanwhile, when I open a page of this hostel I do not see the information anymore. I have to click at the location, select arbitrary location in the city center on the map and only then will I see the distance between hostel and that location. As a user, I experience a huge gulf in evaluation that forces me to take a numerous extra steps.

this null effect is caused by a weak manipulation and ineffective internal validity. in a scientific study, as the one dr. morimoto is trying to perfom, internal validity refers to the confidence placed in the cause-effect relationship and to how well an experiment is done and able to eliminate confounding variables.
