Customers are often pushed towards a particular product due to marketers amplifying the FUD (fear, uncertainty, doubt) state.

1. They claim the product is backwards compatible, or is fully compatible with a variety of hardware, implying that the competitor's product isn’t.
2. They claim that their product requires minimal training of employees.
3. They try to sell the worth of the product by claiming that millions of customers use it.
4. They try to hasten the decision by giving limited time discount offers.
5. They play the ‘limited stocks’ game or suggest how others have benefited from the same.

Instilling fear, uncertainty and doubt in the minds of people isn’t new. Governments and political groups have been fearmongering for centuries.

Most mainstream media carries a certain narrative or agenda in their news reporting, promoting the feelings of FUD in readers in order to coax them into buying the publication, clicking the article link, or simply believing the propaganda.

Spread intentionally and unintentionally, FUD (fear, uncertainty and doubt) techniques are quite common. Some of the most utilized techniques to create or amplify FUD among people are:

1. Making negative statements about a rival.
2. Pushing the narrative on possible negative results, while exaggerating the impact or likelihood of the same.
3. Amplifying people's existing negative emotions.
4. Confusing them through lots of information.
5. Questioning their beliefs.
6. Attacking their source of information.

FUD (fear, uncertainty, doubt) techniques use various belief patterns and cognitive biases already present in people.

1. Authority Bias: People are already conditioned to believe authority figures.
2. Bandwagon Effect: People often do what others are doing.
3. Slippery Slope Argument: Suggesting that a certain action can set off extreme results, pushing us towards the wrong path.
4. Appeal To Emotions: Most manipulators appeal to our fears, exploiting our emotions for their gain.
5. Reverse Psychology: Indirectly coaxing people to do the opposite.

We first need to identify the various fears, uncertainties and doubts (FUD) we have in ourselves, trying to resolve them when we know what they are and from where they are coming from.

One can deploy the principle of cui bono, asking yourself ‘who benefits?’ from this FUD being created in you. Likewise, various cognitive biases can be dissected.

Keep in mind that people often believe what they hear, and only object towards something wrong if they have full knowledge of the same and can therefore identify the error.

1. Be clear and objective about your product or service and what the features are.
2. Answer common questions through a collection of Frequently Asked Questions (FAQs).
3. Offer demos so that customers can themselves make up their minds about your service or product.
4. Having customer testimonials and a good website also helps in reducing FUD, also known as the halo effect.
