1)You have named the primary disadvantage - someone else reading things that you don't want read. You can guard against this by making sure you do not write things that are abusive or untrue. Plus don't leave the thing lying around.
The advantage is that it keeps your memories fresh, regrettably we all forget things over the years that we thought we would always remember - keeping a diary makes that possible.
And your children and grandchildren will love to hear stories about when you were young
2)If a person writes things in it that they don't want other people to see, then they should take the effort to properly keep it hidden from other people. Actions can be taken to prevent this breach of privacy.
Keeping a personal diary is useful because it allows a person to reflect on thoughts, feelings and events, and allows a person to organise them. It can also be a record of events, which makes it particularly useful to a person with poor memory (such as myself).
I personally don't see any disadvantages to keeping a personal diary. Yes, someone may find it and use it against you, but as I said there are ways to prevent this from happening. That said, if a person has done something that could result in them being dragged to court, prosecuted and imprisoned then they deserve it and I would applaud the person who had the nerve to admit to invading the person's privacy and bringing them to justice.
3)Have a little read: ... Advantages and disadvantages of different methods of research Observation Advantages The advantages of this research are that you are able to witness the data yourself. This means you have stronger proof whether or not your research is correct regarding the data you are collecting as you have seen it and witnessed it yourself. The research is recorded and observed by the observer. Disadvantages The disadvantages are the research may take a lot of time, it could take weeks or even months in order to have strong based evidence. Another disadvantage can be if you don't have a camera or anything and if you are doing the observation yourself, you will have to constantly keep observing on the times you have planned to do so. This could prevent you from doing other things and may take up most of your time. Questionnaires Advantages The advantages of questionnaires are that they can provide you with the data you are looking for. They are also easy to fill and use. They can also be easily evaluated and analysed after they have been filled in. Disadvantages The disadvantages for this type of research are when filling out the questionnaire people may not always be truthful and honest. This could lead to the data provided being false and invalid. Diaries Advantages The advantages of writing a diary regarding your research will be the information provided by the researcher will be true and real life events would be written and the researcher will also provide their views and opinions on the issues. Disadvantages The disadvantages will be that the research provided by the researcher in the diary will be biased as everyone has different views on different things. The information provided will be biased because it will be from one point of view which is the researcher's point of view. The researcher will only write his opinion and views, this will be unfair on others because they may not agree with the researchers opinions and may have different views on the issues. Interviews Advantages The advantages of this research are you can ask questions to the person you are interviewing there and then. This will provide you with the information you are looking for and will be reliable. Disadvantages The person you are interviewing may not know the answer or may not want to answer it correctly and therefore give you wrong false answers.
Advantage of keeping a diary is that writing things down forces you to be more precise.
