Manual Review

What Is a Manual Review?

This simply means manually reviewing information. In the context of fraud prevention, a manual review is when a human – say a fraud analyst – is called to review the data and take specific actions, and/or make a decision. 

These days, a manual review can take place after an algorithm has looked at the facts and decided it cannot make a confident decision or guess. 

From there, the case is flagged for manual review – which will itself result in approval or decline, or even additional steps. 

However, in the past, manual reviews have often been the full extent of some organizations’ anti-fraud strategy, with analysts having to deal with long queues of users and actions that required individual investigation or approval. In fact, this still happens today, albeit to a smaller extent. 

How Do Manual Reviews Work?

A trained expert will look at all available data points and reach a decision. This can involve several diverse steps, including:

  • Examining all the data provided by the user
  • Calling the user on the phone
  • Conducting OSINT searches to verify the user
  • Sending the user an email or SMS and awaiting a reply
  • Investigating the reasoning of a whitebox machine learning system 
  • Fine-tuning whitebox algorithms based on manual review learnings
  • Approving declines and blocks by automated systems
  • Reversing bad decisions made by machine learning systems 
  • Speaking to customers directly to explain how and why they need to take additional action  
  • In the case of chargeback disputes, examining the user’s actions more closely
  • Considering complicated cases and making decisions on grey areas

The resulting intel will mean taking action such as canceling orders or transactions, as needed, or even refunding them – as well as letting legitimate users through by approving them.

Manual Reviews vs Machine Learning: Which Is Better?

Each has its uses. Machine learning is better for instant results and large volumes, while manual reviews are ideal for improved customer experience and more complicated cases. Looking at each more specifically…

Manual reviewMachine learning
Time-consumingInstant
Resource-heavy: workforce, work hours One-off investment & maintenance 
Less likely to result in false positives/false declinesMore likely to result in false positives/false declines
Logical, personalized Sometimes illogical – can block users with no real reason 
Personal, polite -> happier customers Impersonal, often lacking communication altogether -> can anger consumers
Works better with fewer cases/smaller workloadsScales easily to handle bigger workloads 
Usually only conducted during office hoursWorks 24/7

How Do Businesses Use Manual Reviews?

Manual reviews are used for various purposes, usually to do with accuracy, customer experience, complicated situations and the individual needs of each company. Some reasons why a business might use manual reviews include:

  • To give a more pleasant experience for users looking to use the site/transact
  • To conduct manual, infrequent reverse email lookups 
  • To do in-depth social profiling including judgment calls, beyond the results an algorithm returns
  • A company might have not updated its legacy anti-fraud systems
  • To deliver good customer service
  • To combine manual reviews and automation, so as to get the best of both worlds

Which Businesses Use Manual Reviews for Fraud Prevention?

Almost every business at risk of fraud can and will use manual reviews, to some extent. In 2022 and beyond, that simply means every business that interacts with its users online – or even, in some cases, offline too.

Some examples include:

Why Are Manual Reviews Important in Anti-Fraud?

Manual reviews will always be important within risk management because nothing really is black and white, and sometimes human insight is necessary to spot fraudsters.

Machine learning and artificial intelligence have advanced by leaps and bounds. However, there are still a lot of situations when manual reviews are the best course of action and continue to have an advantage over any existing algorithm. 

  • Anything to do with customer service
    A fraud analyst can pick up the phone and speak to your customers, which the latter will find reassuring. Even if the decision is made to block them from proceeding, this can be done fairly gently – unlike when you receive an automated message that your account has been locked or transaction rejected.
  • Improved precision
    Simply put, machines might be smarter than humans one day – but they are not just yet. And they are easier to fool. Manual review can be a good extra step after your risk rules have flagged someone, because a human is more likely to be able to make the right decision when there are grey areas and judgment calls.
  • False positives can ruin your system
    Machine learning feeds its results back to itself. This means that if it flags a false positive or false decline and there is no manual review to reject and reverse this decision, the bad information will be fed back to the system, effectively training it to make mistakes more often – a negative machine learning loop, if you will.
  • Always whitebox
    If you’re utilizing blackbox machine learning, it is impossible to know why the algorithm has reached each decision. A human can always explain their reasoning and, if mistaken, learn from this. In this sense, manual reviews are always “whitebox”.

Are Manual Reviews a Good Anti-Fraud Strategy?

As it happens with so many real-world questions, there is no black and white answer. 

The optimal approach is to combine the two, acknowledging the benefits of both machine learning and manual reviews and using them in tandem, in a comprehensive workflow where rulesets and artificial intelligence support human intelligence. 

The result? The best possible combination of quality user experience and efficient fraud protection. 

An impressive 80% of consumers around the world firmly believe that the buying experience is as important as the products or services bought, according to Salesforce. And, per Accenture, 33% of

consumers who abandon a business relationship do so because they do not feel there is enough personalization.

Manual reviews both decrease customer insult rates from false positives and provide a vastly improved user journey compared to only relying on automated rule sets. For many organizations, using risk rules and manual reviews side by side is, simply put, the very best option.
