I support this conclusion.
Why am I taking this seriously, but I support this
As a failure and a disappointment, I support this bitterly.
as a farmer, I support this.
as an unemployed person, I support this.
as a person who knows nothing about engineering or research, I support this.
As a person who doesn't listen much to class back then, I support.
As a severely depressed person, I support this.
As an engineer, Heewon's conclusion about being a "promiscuous guide" is not fully backed up by his experiments. The range and data is insignificant as there is no control variables and only one set of data is procured. He did not fully explored possible tests such as; doing it with another person, interviews with a large sample of espers and guides, heck, he didn't even fully define what constitutes as promiscuous behavior.
In conclusion: I say, he does it again, possibly multiple times to see if there's a correlation. Extending it to using other subjects is also recommended (optional).
