I don't believe in it, it is purely non-scientific.
However saying that astrology can actually effect a person in a psychological way. It has been proven that if a person expects something to happen they will either always be on the watch for it or in someway cause it to occur, or both. In otherwords people who read that 'there will be some emotional hurt this week' are more likely to be upset by this and act a certain way towards others, which may inter reactions that would be somewhat negative MAKING the person feel emotionally hurt by how everyone is treating them. In the same way someone who reads that its possible that they may break up this week are likely to increase tension between them and their partner.
