If Octopus will be deciding the outcome of world football matches in future also it will not be a surprise.
The reason is simple. People say all the 23 predictions that Octopus made came true. I dint follow them all but I believe what was shown in the most advanced global TV channels : they showed the octopus before and after the news.
What is Octopus theory?
It has three components:
1. Asking: we are asking an animal to predict the outcome of a football match (I am not sure if Octopus has ever seen a football match)
2. Start believing that taking food from particular box is signs of winning of a particular team. (If 10 million people have that belief in their mind its real great achievement of advertising of that belief).
3. Outcome: I have seen the fans, teams playing matches (at least some of them) and believe that best teams won the matches ( luck apart) .

Perhaps Octopus predictions created a psychological fear of defeat or joy of victory in minds of millions of people that created positive energy and negative energy.
Recently I read a book which said you can achieve what your mind strives for in your thoughts feelings, emotions and imaginations. If you imagine to be rich and successful, you are going to be rich and successful. Its what the author has said.
Could it explain the Octopus theory ?
I am very keen to know scientific basis of Octopus predictions.
