Interesting. So you are trying to say there is no human intervention while evaluating Listening/Reading tests? How does it technically work?
There does remain human intervention in evaluation of L R, but the difference is that the answers are ALL OR NONE, i.e. either it is 100% correct or 100% wrong. There lies no subjective aspect in this. They have hired some clerical staff (of course trained one), who evaluate the L R answer sheets. Also, these staff are provided with an answer key, according to which they evaluate the answers. So, if your answer matches with that of the answer key, then bingo, your answer is correct. Otherwise, not. Even a small mistake in only one alphabet letter/number can get you a wrong answer.
On the contrary, the evaluation of S W is solemnly dependent on human subject. The examiner evaluates your task response in both of them. SO, naturally, there lies subjective aspect. It is obvious that while one examiner finds you eligible for 7 in S, at the same time, other examiner may not. The other one may give you 6.5 or even 7.5...
These are the reasons why experts sometimes advise to go for re-evaluation of S W, but not of L R.
Hope it helps..
