Development
 While there is still disagreement as to what factors characterize  incidents that contribute to the development of Stockholm syndrome,  research has suggested that hostages may exhibit the condition in  situations that feature captors who do not 
abuse the  victim, a long duration before resolution, continued contact between the  perpetrator and hostage, and a high level of emotion. In fact, experts  have concluded that the intensity, not the length of the incident,  combined with a lack of 
physical abuse more likely will create favorable conditions  for the development of Stockholm syndrome.<sup id="cite_ref-FBI_bulletin_0-1" class="reference">

 The following are viewed as the conditions necessary for Stockholm  syndrome to occur.
 
- Hostages who develop Stockholm syndrome often view the perpetrator  as giving life by simply not taking it. In this sense, the captor  becomes the person in control of the captive’s basic needs for survival  and the victim’s life itself.<sup id="cite_ref-FBI_bulletin_0-2" class="reference">[1]</sup>
 
 
- The hostage endures isolation from other people and has only the  captor’s perspective available. Perpetrators routinely keep information  about the outside world’s response to their actions from captives to  keep them totally dependent.<sup id="cite_ref-FBI_bulletin_0-3" class="reference">[1]</sup>
 
 
- The hostage taker threatens to kill the victim and gives the  perception of having the capability to do so. The captive judges it  safer to align with the perpetrator, endure the hardship of captivity,  and comply with the captor than to resist and face murder.<sup id="cite_ref-FBI_bulletin_0-4" class="reference">[1]</sup>
 
 
- The captive sees the perpetrator as showing some degree of kindness.  Kindness serves as the cornerstone of Stockholm syndrome; the condition  will not develop unless the captor exhibits it in some form toward the  hostage. However, captives often misinterpret a lack of abuse as  kindness and may develop feelings of appreciation for this perceived  benevolence. If the captor is purely evil and abusive, the hostage will  respond with hatred. But, if perpetrators show some kindness, victims  will submerge the anger they feel in response to the terror and  concentrate on the captors’ “good side” to protect themselves.<sup id="cite_ref-FBI_bulletin_0-5" class="reference">[1]</sup>
 
 In cases where Stockholm syndrome has occurred, the captive is in a  situation where the captor has stripped nearly all forms of independence  and gained control of the victim’s life, as well as basic needs for  survival. Some experts say that the hostage regresses to, perhaps, a  state of infancy; the captive must cry for food, remain silent, and  exist in an extreme state of dependence. In contrast, the perpetrator  serves as a 'mother' figure protecting the 'child' from a threatening  outside world, including law enforcement’s deadly weapons. The victim  then begins a struggle for survival, both relying on and identifying  with the captor. Possibly, hostages’ motivation to live outweighs their  impulse to hate the person who created their dilemma.<sup id="cite_ref-FBI_bulletin_0-6" class="reference">

 In many cases, capture may also involve the killing (or threat of  killing) of the captive's relatives, thereby isolating the captive. The  captive is subjected to isolation and so sees even a small act, such as  providing amenities, as a great favour. Such captives may side with  their captors while believing their captors have conferred on them great  importance and love. Furthermore, captives who perceive themselves as  the only members of their group not to have been killed may believe that  they have been shown a special interest. <sup class="Template-Fact" title="This claim needs references to reliable sources from November  2009" style="white-space: nowrap;">[
