- Perspectives of Others A Case Study in Noticing blind spotothersperspectivesothersâ perspectivesothers
----- case study (Mr. Nakayama)
- At some stage T1 of the project, a decision was made that a certain policy X was no good. This decision was appropriate under the circumstances at the time.
- Later, when the project was considered for a policy change, Policy X was not a candidate.
- I was talking to someone else and asked, âWhy not Policy X?â I realized that I had not been a candidate when they asked me.
- Upon review, environmental conditions have changed between T1 and now, and policy X is now the appropriate solution.
Because of the memory/experience of âwe considered Policy X in the past and decided it was a bad idea,â we subconsciously ignore Policy X. Experience creates blind spots. I realized that I was blind to Policy X from the perspective of someone who did not have the experience of judging it to be no good.
At T1, the conclusion should have been âPolicy X is no good because of condition Aâ, but before long the human brain forgets âbecause of condition Aâ and rewrites it to âPolicy X is no goodâ.
----- case study
- Look up technical information on the Internet.
- Find the same question on a question answer site. It has a high rating for the answer.
- I thought this was correct and implemented it, but it doesnât work.
- When I asked someone in the know, he pointed out that the information was out of date. (Specifically, Android 4 series code does not work on Android 5, APIs starting with NS are obsoleted, etc.)
- The idea is that the article was correct at the time it was written, the social reputation is positive (because attention is focused on the article immediately after it is written), but if you reach the article through search after some time has passed, the assumptions have changed and it is no longer correct.
----- case study ---Premise Submission Questions raised during the Q&A session at Tokyo Metropolitan University
- Q: Can you give me an example of a communication with another person where you noticed a blind spot that led to a solution to a problem?
I struggled with this question for a while but couldnât think of anything appropriate at all. I thought about what the reason might be.
- The first assumption is that âI didnât come up with a solutionâ to a problem that is âdifficult enough that I canât come up with a solution quickly enoughâ.
- I would have taken the time to explain the issue beforehand, provided that others understood it and advised me on it.
- Advice was given from a different perspective than mine, but it is difficult for me to explain the context in which it came from because it is a different perspective than mine.
The problem is difficult to explain & it takes time to explain the problem & I have difficulty explaining my advice, it is difficult to give a quick example of this type of event in a question and answer session.
Examples of âI seeâ on a scale that is easy to talk about.
- When I saw a solution to the problem of getting scammed when traveling abroad, instead of fighting the scammers on the spot, pay with a credit card and contact the credit card company to stop the debit, I thought, âI see.
- This is not the solution to my problem, I guess.
- Because it is not a solution to my problem, it does not require the cost of explaining the problem, and as a result, it can be explained in a handy size.
Reaction of a friend (Nakayama Tokoroten) to ----- story 1
- T: Whatâs the difference between a solution Iâm not aware of and a blind spot?
- N: I donât distinguish between the two.
- N: In terms of sets, blind spots are a larger set because they include âissues that need to be resolved that I am not aware of.
- T: If thatâs the case, shouldnât we focus on a subset of âissues Iâm not aware ofâ cases? We are expanding the concept too much and itâs starting to poof out.
- N: I see!
explanation
- Until the question was asked, I had been using the term âblind spotâ and âissue to be solved that I am not aware ofâ without making a clear distinction between the two.
- And they were unaware that they were âusing it without clear distinctionâ.
- When asked the question, he first answers, âI donât distinguish between the two. However, after a little time, he began to think, âI said I didnât distinguish, but is it equal?â and then he answered, âIf it is a set, thenâŠ
- When you say that what you thought was equal as a set is not equal but an inclusion relation, there is something there that you have overlooked.
