1 articles that A can lead to B, but did not rule out other causes the possibility of B, these other causes include C, D, E. When the C, D, E exists, the original thought A leads to B is untenable.

2 authors derived data may not be representative, because the data does not have to be in when time, when locations in the right way to investigate the right people. Due to the lack of the effective data obtained information, is unable to draw the conclusion. For example, if the results of the survey involving 2000 people, but 20 people; if the survey work, but the investigation was night time; if the population are white-collar workers, but went to university campus interview; if suitable for investigating the way is one to one, and is filled with questionnaire, in these circumstances, conclusion be suspected of. Until we all mention of the problem was resolved after all, the data to perfect evidence to prove the conclusion.

3 authors to form conclusions are based on an assumption of A, however, in this paper, there is no evidence to prove this hypothesis is true, we can see hundreds of examples of BCD, when these assumptions are not any evidence to support, to draw the conclusion is arbitrary.

In 4 the original conclusion to establish, contains the following aspects, 1, 2, 3, 4, and in this a few aspects, apparently 1 and 2 are the most important, and it is the most important aspect is established in this paper and the absence of any data. In the absence of sufficient evidence to prove that it is the most important aspect of its situation, draw the conclusion is not suitable.

5 the A to launch B is too arbitrary. The text thinks, because A occurs in B front, so A can result in B, but only the time difference that A and B in the presence of relation, is not correct. Unless there is evidence that the two events in the presence of causal relationship, or just because of the time, that A can launch B is relatively arbitrary and untenable.

6 original arbitrarily think A can lead to B, but in the original text and no evidence of B may lead to A, for example: X. A occurred in front of B, but not B leads to A can not, unless we can prove that B did not cause A. Or that the A can result in B, A certainly is because, B must be fruit, is untenable.

7. Conclusion: A and B in all respects is similar, but this view may be untenable, because in the A and B in the comparison process, we will find that, although there are some similarities, but no similarities also meet the eye everywhere. For example : no similarities between the 1, no similarities between the 2, no similarities between the 3, so, by a ratio of B, come to a similar conclusion, is be inopportune or inappropriate.

The 8 authors, either A leads to the conclusion of the article, or B leads to the conclusion of the article, without the presence of the intermediate state of the possibility of statements, but the article does exist in the intermediate state probability. Life in a large number of experience will tell us, is not a A or B, but A and B combination can often produce more ideal effect. For example, in 2000 the negotiating parties in A to increase sales, B would like to increase the sales price, lead to double reverse do not recognize, but a combination of the two may be able to achieve a win-win situation.
