Answer:
The answer is identical twins.

Although positivity is important in a business report, it can make the report seem unprofessional, can impair the writer's judgment, and can make the report seem too enthusiastic are some of the common drawbacks of too much positivity.
The main drawback is not because of insufficient hope or the existence of weak self-confidence. It is due to the factor of excessive optimism. Whenever you are more ambitious about your goals, you will be more confident you are likely to feel about accomplishing them and you will expect more to benefit from doing it and ultimately resulting in less chance you are to be succeeded.
Those who skew more pessimistically about reaching their goals on the other hand may be more likely to achieve them but not least although their self-doubt encourages them to work harder to reach their near goals. When you want something really, you would be better thinking off that you would not get it than assuming you will reach near.
As same as in the case of business reports, too much positivity can ruin its success as the report will now become unprofessional and can impair the judgment of the writer.
